Appearance of process invocation

[colinc]

I have various business processes created, that I include in other processes to try and show common processes.

When I select invocation of a process, ie. describing a particular instance of the process, the appearance changes to a rectanglish object with a fork in the corner.

Is it possible to have this appear with the same appearance as the original processes, it is confusing for my business users as to why their is a new , unfamiliar icon type.

Thanks, Colin
