A way to create left or right indent for systems, other than using frames

Your idea

I want to propose the following feature:

Allow to create a left or right indent for a system by

a) dragging the first or last barline of a system, which is embraced by sytem breaks

b) selecting a system break - I'm mean the layout symbol - and adjusting a new inspector setting, called:

• "right sided indent for current system"
• "left sided indent for following system"

My idea with b) is:
A system will always break where there is a system break.
Because of that it could make sense to link (and restrict) a new "indent"-setting for the inspector
to the system break-symbols themself.

Problem to be solved

Creating an indent in MU is quite laborious and could become
easier and more intuitive, for example:
