Justifying/aligning SA staff names

I asked this question in 2019 and still haven’t found a solution.
In an SATB choir piece on two staves I need to have the S and the A centred instead of right-aligned. In Finale there were two sets of settings for staff names, one for aligning and one for justifying. In Dorico it seems that one can only justify the names. This is the desired result (from a Finale file):


This is the result in Dorico with the staff name paragraph style set to centre:

The SA are properly aligned but centring includes the Piano staff name which places the SA and the TB too far from the staves.
This is the result in Dorico with the staff name paragraph style set to right align:

The positions of the staff names are now correct but the SA is wrongly aligned. The only way I can think of to get around this is to remove the Piano staff label, which actually isn’t a solution at all. Am I missing something?

No, you cannot both centre the staff labels on each other and then right-justify the staff labels, as things stand. We would need to implement this as a new feature.

If you set the alignment of staff labels to centered, you could simply add several spaces in front of S, A, T and B to move those letters to the right:

Thanks for responding, Daniel and John. @johnkprice: that does work but it’s a bit of a kludge involving trial and error, not really in the spirit of Dorico’s UI. I’d like to make the feature request that both alignment and justification are independently possible, and also that when staff names are more than one line, they centre vertically, as well. In my examples, both the SA and the TB are too high. Sure, setting a baseline shift of about -2 points for both staves will take care of that, too, but once again, it’d be nice if that weren’t necessary.
