TL;DR
I would like to be able to copy an Assembling Machine and have it's recipe paste to a Storage Chest filter or Circuit Network signal.
What ?
For this setup which is common to my bases:

It would be nice to copy the Assembling Machine's recipe and paste it to the Storage Chest's Filter.

Given that assembly machines already paste to Requester Chests, this falls in line with current behaviors.
I would also like to be able to paste the recipe to a wired inserter and have it default the circuit condition for that inserter.

Why ?
I like to produce set amounts of things. As such, I'll set limits on my output chests for the things I am producing. In this example, I will never need more than 2 personal roboports, so I limit the inserter from the assembly machine to the provider chest to only allow storing 2 of them.
In the cases where logistics robots grab those from the chest and begin delivering them to me, and I go out of range, I want those returned to the production site, not lost in a storage chest dumping ground with dozens of others who have suffered a similar fate and do not contribute to the limitation on the inserter from the assembly machine.
This may seem like a silly use case, but I do the same for nearly everything I produce: Belts, Inserters, Rails, etc. In this manner, upgrading (or deconstructing) something does not result in yellow belts being flung to the far corners of my base where a random storage chest happened to live, they are instead returned to my belt production area for re-use as an ingredient to replace the red or blue belts I just upgraded to.

These setups are tedious to create. Build the assembly machine (and inputs), set it's recipe. Then build a provider chest, a storage chest, and their inserters. Then run a green wire from the provider chest to the assembler's inserter. Even assuming that part was accomplished with a BP, you still have to then open the inserter and find the object which I just set the assembly machine to produce and enter my quantity. Then open the storage chest and again, find the same item - knowing that filters use a different 'remembered pane' than circuit network selections which is also different than the assembly machine's recipe pane.
Even late game, this would greatly speed up the placement of my bot-construction blocks. Since I am already able to copy the Assembly Machine and paste to the Requester Chest, each new item I tell the bots to produce would be decreased to one shift-right click, 3 shift-left clicks and then only opening the inserter UI to set the quantity I want the provider chest to contain.

Mods
The only mod I found which is similar is the
https://mods.factorio.com/mod/Autofilter but this operates by setting the filter of a Filter inserter, not the circuit condition of a standard inserter nor the filter of a chest.
