Suggested here

Suggestion only said glass blocks but it could be any block state perhaps?

Applying from item stack
Probably has to be an itemblock, consumes one item.
Might not be versatile...

Probably activate holding an item then shift + P

Alternative:
A tool that copies a block state then applies it to plonked items
When holding the tool, disguised blocks are shown.
I like this more, but not sure if this is easy to implement but will see.
