Push pull ?

Hi there,

I was wondering if it's possible to do something like the Push Pull in sketchup.

You pick a closed curve (or a surface) on a solid

or

You pick a closed curve (or a surface) then select a solid

Then

Extrude in one direction = regular extrude
Extrude in the direction of the solid, once you intersect with it = extrude then boolean

Instead of calculating the boolean in real time it would just display the hidden line (kinda when you use the move command)

Sound possible ?
