Move bar numbers further to the left?

I can find the option for vertical bar number placement, but for the horizontal placement there are simply 2 options. Is there a way to fine-tune the horizontal position? From what I see there is no way to select all bar numbers at once in Engrave mode – or do I miss something?

Use the First Line Indent in the Paragraph Style for Bar numbers.

@benwiggy Thanks! But… hmmm… that only moves the number within the circle. Not quite what I am looking for. (And using a border on the number itself is not nice either.)
