As its a global for your squad I would assume no as it'd require a rather complicated addon to allow you to set static amounts from the squad pile to each member and have it update upon each raid.
To add such into the game in a way where only one char has the cats and had to pass/drop it to another member for that member to be able to haggle with it the squad would have to have another variable stat added for wallet/purse which would add any number of bugs.

This would make many of the interactions much more tedious.... but more like dnd.... cept GM's tend to prefer using "party" gold as its easier to keep track of....

I think this would work if every cat you collected popped up in your inventory! that way you would have to keep them all in a new type of cat storage and then all the money you would make at that outpost or town would stay there until you got robbed or something. if you wanted to buy something you might have to aquired a cat purse to avoid hauling 2 inventories of cats to purchase a new leg. would add another risk factor to building an outpost and it would make training without a house tougher. what im thinking of could be made from assets already in the game, safes and bags could be repurposed to act like designated storage containers for cats. you could have different levels of safe lock research and then if your outpost got raided the raiders would have to either cut it or pick it if they want your money.
