Fit custom pattern into a area? Stretch / Squeeze into area or How to Align 4 points

Hey guys I'm looking for help trying to "Squeeze" or "Stretch" a pattern into a area. Or in other terms how can I align 4 points and scale? If I use align and I take 2 points of a selection and "Align it" to a smaller line it scales it.

please view attachment, lets say I have several rectangles and want to have a 4 point scale, if I had the option to do that then the pattern would fit into my empty area and top would create a trapezoid.

Attached is example, of course square rectangles are easier shapes, but I'm trying to figure out how to do this with abnormal patterns. Have a effect basically get smaller as it goes down or get bigger.

Im using these for laser cutting small objects that are 2"-5" by 20" .

ONLY working with 2D. no 3D work
