[Suggestion] Adding an additional field? variable to meg:setitemmodel

- meg:setitemmodel{mid=testmodel;bone=examplebone;i=STONE} @self

Would be nice if we can add the custom model data to the item as well!

Maybe something along the line of - meg:setitemmodel{mid=testmodel;bone=examplebone;i=STONE;model=1} @self

This helps and solve a lot of issues of people trying to do custom shop display stuff... 📦 and not having to create 90000 mythic items to display custom model data
