Configure category separator on startup.

Due to “reasons” beyond my control the naming convention from an external party (who publish on our EventStore instance) publish on streams where the word separator is “-”. This created a lot of extra throughput on the category topic. We found out we can reconfigure the separator by overwriting the corresponding projection, we used “|”. However it seems for internal projection the “-” separator is still used. I’ve tried to look up the configuration options but it does not describe the initial separator option. Is there such a thing?
