Hologram Items! (like schematics in minecraft)

I was thinking, what if we had a system, where you can place items before you bought them. They will look like a hologram, and when you looking at them, there will be prompt:

[cost]
Buy
if you have any amount of them already, it will say how much do you have them and “place” prompt.

if you had any item placed in condo, and it dissappeared somewhy (for example, you sold it while was on plaza and forgot about it placed in condo), it will warn you on joining condo, that [any item] is dissappeared, and it will be saved as hologram (also with settings)

There’s some concepts, how it would look like:


Hologram, but its supposed to look like hologram effect from Event Horizon map.

This might be logistically tricky but I think it’d make for a good feature.
