Users don't want coverage path origin to display

[sshipp]

I have some users which don't want to see the originating stations id when a call has gone to cover group. Is there any way I can stop this showing?
The users have either 1608's or 1603's

The call flow is
call in to station -if not answered - coverage path - cover group

I've checked as much documentation as I can find but no joy - maybe it isn't possible
