[Suggestion] Mechanic "setDisplayItem"
Summary
A new mechanic for displaying entities called "setDisplayItem" will change the item of a display entity. Currently, there is already a similar mechanic, but it only applies to projectiles.
Usage
It should look like this:
- setDisplayItem{item=MYTHIC item or a vanilla one}
Value
Display entities are the future of Minecraft, and this mechanic is really important
Priority
Kinda important? at least for me it would be, I need this mechanic and I currently need to use the console "command" mechanic.
