How to control the gap between the intensity mark and the prefix within a dynamic marking

[prko]

Hello,

I would like to input the dynamic marking mp–pp. Since Dorico does not support this as a native combined dynamic, I have added a separate dynamic with a prefix to the right of the main dynamic, as shown in the screenshot:

However, the gap between the intensity mark and the prefix is too wide. Could you please advise me on how to adjust this spacing?

Many thanks.

It might be an idea to build this combined dynamic as a playing technique, using glyphs.

Yes, although it would be ideal if Dorico also supported mp, p, and pp in the same placement options as mf, f, etc.
