The problem: You have no direct control over where bots dock themselves.
The suggestion is simple: allow us to order docked bots, that is, the bots which aren't in chests as items, but sitting in roboports. This way, I can easily collect them from a network. Example: I would like x logistic and y construction bots for a mining outpost I am setting up. I don't want to run around looking for them, so I set my personal logistics to requests these bots (they have a special icon in the entity list). The bots ship out and insert themselves into my inventory.
Extended suggestion: We can set these requests inside the roboports themselves. Example: I set each of my ports around the perimeter of my factory to request 5 construction bots. This will ensure an even distribution of them close to my walls.
Alternate suggestion: Docked bots offer themselves to fulfil orders if there are no more bots in storage. For example: There are 10 logistic bots in storage. There are 50 docked in a port. I order 20. The 10 from storage get delivered to me and then the 10 others insert themselves. I do not like this suggestion as much as the first as it gives less control as to where the bots come from, but it may be simpler.
