Update Equipment Item UI for Valid Grids

[Pirate_Rance]

TL;DR

Please update the UI on items that are able to be placed in equipment grids to instead show the category of equipment they are.

What ?

My suggestion would be to instead make the item show a image/word of the type of equipment category they are. And to have in the actual grid screen have a marker list of the equipment grid categories that are valid for the grid.

Why ?

ATM equipment that is valid in grids lists every unit/item that the item can be placed into. This causes a HUGE list with longer mod lists going far off the screen making it so equipment checking is not feasible with larger vehicle/armour lists in the game.
