TL;DR
A switch, just like "Auto trash and personal logistic" on/off, that, if activated would automatically lower item's "Minimum requested amount" as it gets used.What ?
It would need to lower the amount in cases of manual building, personal construction bot building, chest/machine/player transfers.Why ?
As it is now if you ie. need X items required to build something or to feed to machines manually, you can set min request to X. But as you spend items bots are being set with new supplies.For now the only way to manage it is to set the required amount to X. Wait until all items are delivered. Change requested minimum to 0 manually. Start using said item.
If there was a switch as proposed, you would be able start working immediately with only one edit to requested list.
For it to work best it wold have to be a per requested item slot to prevent unintentional lowering of other requests. So a checkbox right beside where you input the minimum requested value.
