This has been bugging me, but I don't know if it is possible to do.....

At the moment in the trading centre and when searching branches you have the option of selecting each individual type of carcass from the list to search for it.

What I would like is having an option to search for all 'food' items which searches for every sort of carcass or meat chunk. Prices would be easier to compare for the buyer, and sales of uncommon small carcasses would be more feasible for the seller.
The option could be applied to the trading centre or the branches item search or both!
