Where are filtergroup specs stored? I know they are in the config file but are they stored anywhere in the database?
The Filter Groups are defined in the profile configuration file only, as XML. Unfortunately there is not a master copy or profile specific copy stored in the sqlite db or analytics database. If there are a set of Filter Group rules that you want to have by default for all future profiles then you can adjust the master profile config (web.cfg) which is used as the template for new profiles.
Hope this helps,
