Would be nice to have the ability to align a filled region within a view instead of grouping the filled region, using the 'Align' tool and then un-grouping.
Can you clarify what you are asking?
Do you mean you draw a filled region and when you use the align tool you want the entire filled region to move over instead of just the one edge?
If that is what you mean, you can add dimensions within the region sketch and lock them.
Or you can make the region a family with parameters to control the size.
Or you can just move the filled region instead of aligning it.
