Invisible but clickable unit

Im having some doodads around the map and wanted to build invisible
buildings over them. The point for doing this is that the doodads can't carry
items but the buildings can. I tried changing the model to wrong path so I get
purple/green the building turns invisible but hard to click, also tried using Buffs ->
Breah of Frost model which is almost invisible but it gets unclickable too : - (

What to do ... .. .

Why not let the doodads have an invisible model... or rather no doodad at all. and make the buildings have that model?

You need a click helper - something clickable in game. It's probably possible to make this model and import it, but I suggest doing what Wietlol says.
