Every time I make a new document- my masters can be complex but the left and right side of the same master are a pain to make exactly the same.

So either make copy and paste work better in masters or add a feature that allows left and right sides to be lined up the same.
I want to be able to set all my parts and then set guides on the left side—
and then copy them ALL- guides, date, page numbers, doc name and other items to EXACTLY paste in the right hand side.
Right now Paste In Place pastes on the left side, why cant I click on the right side and paste in exactly the same alignment?
Right now I have to group all together then nudge a pixel at a time.

THEN check the pages to see if anything jumps, Then adjust and adjust.
Masters are archaic right now. They could be WAY BETTER.
