Score Editor: Auto Layout → option to keep grand staves as they are

When I execute “Optimise all” or “Spread Pages” I always end up with grand staves (piano L&R) that look unusual. That is, the left hand staff ends up being placed at a too farther distance below. If I had an option to ignore the space between the staves of a grand staff, I would use alt+drag to ajust the grand staff on all pages/lines, then execute the “Optimise All”/“Spread Pages” function. This surely would improve the look of my score layouts…

Thank you.
