Musicals symbols change / Combined dynamics

Hello, sorry for my poor english.

I’m trying to change the defaults dynamics symbols by my owns.
All is well for individuals dynamics (p ; f ; mp etc.) and dynamics with textes.
Nuances 1.png
But combinated dynamics are superimposed.
Nuances 2.png
The excel sheet attached shows you what I changed (in black) and what I left by default (in red).

Can you help me to have beautiful combined dynamics ?

Thank you in advance, all the best.

Hi Matt, welcome to the forum. You want to accomplish this without the suffix function in the Properties panel?

Also, much of this functionality is already present by simply typing the desired text into the popover.
