Feature Request: Stacked layers with fixed width/height?

[ajmoo]

Feature request / enhancement

I have 4 objects that are spaced with 32px padding between them, centered in a 375 canvas. This stack is a total of 352 in width.

If I duplicate an object inside the stack, Paddy does what you would expect: Moves the object over and spaces it out with 32px padding. This increases the overall width of the stack to 424px.

What I would love is for the option to denote a fixed height/width stack, with objects inside spaced
out evenly instead of a strict pixel amount.

I apologize if this is a duplicate request.
Thank you!
