FRO- SRO decrese/ increse button- how to change % step?

[MozaPrime]

Hello.
Is there any way to change the operation of these buttons?
I want the value to be changed by, for example, 5% (or any other number) after pressing the button, not 10% as is standard.

You'd need to write a macro for each button, and change the button number to call the macros.
