Another thing I thought was with certain 2da files IE stacking you can make potions/healing kits higher stack with out a hak file. Its when you make new item,texture,model etc you need hak correct.
I'm still waking up so I hope my answer here makes sense and addresses your question...
On Mythos I manually increase the shop stocked potions, scrolls and healing kits stack size from 1 to 10. You don't need a new blueprint for the items to do this. Stock the shop with the goodies that you want, then while editing the shop, edit the particular potion/scroll/kit. From there you can increase the stack up to 10, which is the 2da default. This works well for shops dropped directly on the map. Not so great for shops generated from the palette. No hak needed. It is tedious work but worth it.
