solving dynamics clash

[Helge Kruse]

Hello,

I write a piece with a StaffGroup where the bar lines should connect the 
 staves indicating the staves that define one instrument. The dynamics 
are written in a separat "voice".

The problem is, that the dynamics clash with the bar lines. This occurs 
at many locations.

Is there a way to adjust the dynamics a bit more right? Since there are 
a lot of dynamics in the piece: Is there a way to adjust this automatically?

A (minimal) example is attached.

Regards,
Helge
