Not sure how difficult it would be to have bundles show an icon on them when everything in the bundle is the same...
For example you have a bundle of boar meat or fox meat that it would show that animal icon on it like a regular piece of meat.
Or say poppy flowers in a bundle that show poppy flowers.
A benefit would be for barter stands and not having cupboards fill so fast. You could buy a bundle of boar meat for X price versus buying X number of pieces of meat for X price and having the cupboard fill up super fast
Could still have the generic look if items in the bundle were mixed
