I take it that it is probably impossible to have them return to a stations workforce? It's not a critical request as one can have a large crew dormitory ship and once in a while when full do it manually.

Hi. In game there is no possibiity to transfer unassigned perons to station.
At list I can't see.
Main reason to rescue them - it is possibility to assign high quality pilots on another ships.
So, to transfer them from somewhere to new ship.

but agree, using the station to "store" saved persons will be the best and logical

Are you open to expanding the mod more?
I'd love to be able to collect all abandoned pilots, not just my own.

Make it profitable or have value:

Enemy (based on standing) can be "Prisoners", which are stored in the Brig (automatic generate based on crew limit, 20%).
Options:
1. Allow me to Press-Gang (convert) them to crew/marines.
2. When I dock to a station hostile them as well, I get bounties, that match their skill levels.

Friendly, are "Survivors", which are stored in "Rescue Quarters" automatically generated w/ limit available cargo space. 2m3 per person + open crew spaces.
Options:
1. Recruit them (IE i pay some compensation to recruit them), same price as maybe filling crew when refitting?)
2. When I dock to a non-player station, they pay me a taxi fee + reward. possibly even special mission's triggered for specific station delivery? [functionally, they can go poof after delivery]

Impressive idea.
Not sure now, but will think about it
