Edit the context toolbar (graphics area)

Hey everyone,

we got a new PDM-System and now I'm trying to change the SolidWorks standard 'open button'

in the context toobar (graphics area) with the new PDM 'open button'.

I want to change the red marked 'open button' (greyed out) with the

other marked button from the PDM system.

Thanks in advance. :)
