Hello !
I am looking for a way to lock a corner/node to vertical/horizontal axis when moving it with the "perspective transform" tool.

Is there such a functionality ?
Is there some way to mimic such functionality with assistants or guides ? (tried, but no result, maybe I'm not looking in the right direction)
Is it planned for development ?

If all the answers are negatives, I'll look at the code to implement this myself since I need this functionality badly.

Thank you for your time.
