Please give us two things:
1. "Send to camp" even when picking up stuff not out of containers (this looks like an oversight to me)
2. Option "send camp supplies always to camp"
While we're at it, this is not camp supplies related, but would also help a lot:
3. Make vendor trash "wares" automatically, too, as an option
Problem is that, especially for beginners, it's hard to decide which is which. I vividly remember carrying a lot of trash around (bones, especially), because I thought that it may be something useful. Of course having a little symbol "trash, but you can sell it" would be helpful, too.
