[Answered] Mark items as don't pick up from missions.

[SembeiNorimaki]

After completing a mission, all objects are taken to the base and stored in the general stores.

At some point of the game, you don't really care about certain objects and they just fill up storage space, so after a number of missions I have to go cleaning storage space because my soldiers took machetes, baseball bats, tonfas, tokarevs, lugers and other stuff I couldn't care less.

Would it be possible for each item to have a "don't pick up" checkbox, so those objects will not be picked up after each mission, of if they are picked up, they are automatically sold/discarted.

I feel it quite tedious to have to sell all those items every now and then, and I don;t want to build more storage facilities because the base has a limited number of sports that I'd rather use for more important buildings.

It is already in the game.

Use the Sell menu at the end of the mission.
If you right click the "up" button on an item, it will remember and auto sell it the next time you go into this menu in a future mission.
