Vertical alignment of commas in 'holds pauses' when grace notes exist

Dear developers and users,

How could I vertically align all commas?
Adjusting start offset x does not always work in the following example:

I have discovered that adjusting x offset after selecting all commas disposed of grace notes works well.
However, it would be great if Dorico does this automatically.
I am wondering if it might be implementable.

Dorico will align the breath marks at the same horizontal position if they are at the same rhythmic position; grace notes are part of the rhythmic position, but if a staff doesn’t have a grace note, that rhythmic position doesn’t exist.
