Is your feature request related to a problem?

When using the ItemSwapper hotkey on a pickaxe, it shows vanilla tools such as the pickaxe itself, shovel, hoe, etc. This works great. However, my mod adds a chainsaw which is basically an axe tool. While supporting every mod is obviously not do-able, my hope was that the mod had a feature to define custom sets in the form of a datapack or json config type file.

Describe the solution you'd like

I was hoping to have something like a config file, like minecraft__diamond_pickaxe.json (just an example), that has a format like:
"target": "minecraft:diamond_pickaxe",
"append": "true",
"item_list": ["modernlife:chainsaw"]

This would then show my normal inventory, the pickaxe, the shovel, but now also showing the chainsaw in the list. It would be OK if this didn't work in reverse - i.e., choosing chainsaw and hitting ItemSwapper would not show the pickaxe/etc. But then I could make a new file or configset with target="modernlife:chainsaw" to manually correct this.

Also, unrelated to the above, I was hoping for a way to sort the item list that pops up alphabetically, such that if I have a pickaxe, shovel, and hoe, the list would popup with these 3 items but it would always be in the order Hoe, Pickaxe, Shovel irrespective of which item I have selected.
