Hi @plivanos and sorry for the hassle with this one.
I'm adding your vote for this request but in the meantime, I thought that I would share a feature that we implemented recently:
Resizing one or more controls to match the size of another can be done using the Resize To function in the Edit menu, as detailed here.
This way, you can change the size of only one control and quickly apply the change to other ones.
Hope this will help to ease the pain! Anything else, we're here.
