Create a OSM subgroup

Is it possible to separate quite a big group of messages beginning with “Osm:Geocoder.search_osm_nominatim” to a separate message group (currently, they are in “OpenStreetMap - Website”, they could go into something like “OpenStreetMap - Nominatim”)? Thanks.

Not at the moment. We can filter away messages with a pattern, but the opposite of that (keeping only messages matching a pattern) is not easy.

OK, thanks.
