Firstly and most importantly: Have food pulled directly from Camp Storage when Long Resting.
There is one tiny problem ... this "few clics" are the only *actual* limitation ...
If you remove the need to carry the food ... bcs you have covenient "send to camp" button ...
And if you also remove the need to pick the food from the crate ... bcs it will happen automaticaly ...
There is nothing stoping you to gather litteraly every single picece of food you find, so you allways have enough ... and dont care about it ever again.
In other words...
You could just delete this mechanic whole and the result would be exactly the same. :-/
