New Dimension Editor Tips
We released our New Dimension Editor (New DE) on PA 2.0.82 with some good improvements compare to our Classic Dimension Editor.
1. Better UI with IBM Carbon Design
2. Performance improvement especially for the large dimensions
3. More options for filtering including sets, levels, selected members, their attributes and security with action like in cube viewer and set editor

Lastly, the Format values could be set from the ellipsis menu either for whole dimension or for selected members.
Select Format column header, then click the ellipsis and apply format for your dimension:
Setting selected member format via ellipsis menu:
Both dimension editors New and Classic ones are available on Workbench for now, we’re collecting the feedback from our users for further improvements.
