Basically, being able to have custom modeled Demat Levers, Flight Panels and TARDIS Panels and Monitors. And other blocks I cannot think of of similar caliber (maybe bookshelf?)

What it would do is allow people to have working consoles that are 100% modeled.

Example: Demat: has a better design. Flight Panel: changed to look like a lever. TARDIS Panel: made to look like 2 different panels. Can you guess what TARDIS that may be?

It could also allow for some other things, like the door block. 

How it could be added: maybe a GMC item, maybe a TCN Pencil(?), when shift-right clicked (sneak+place block), it will allow for the TCN Loader to show up on the block. Maybe people without the model see the normal block with the TCN "Missing Model" texture.

I got this idea when I realised how out of place all the monitor blocks are on the classic console, and how out of place everything looks in comparison to the spinning lever (Toyota).

Thankyou for reading this suggestion.

I really love this suggestion

Same, has my vote.

Very good idea! I'd actually like to see this implemented aha. Though I don't know how hard that would be to code.

I would add one detail.

Maybe to other users, the mounted block will appear normal (so to them your console won't be covered with "missing model" blocks to someone else, haha.)

 My Toyota console is already like that, but it would make it less "messy" to the unmodeled eye.
