Generate Reports based on Client Not Client/Matter

SOLVED

In our Timeslips we have client matters setup as the name of the Client first then a "/" then the name of the matter. This allows for us to do consolidating billing and also to use the master as a template.

However, it makes generating Client specific reports difficult, because to the reports all those client/matter are separate clients. I'm wondering if there is a way to group them by the client name (the words before the /) and ignore everything after the slash?

Thank you for any help.
