This werk is incompatible for users that use file grouping and single file aggregation
and have "%s" in the section name.
It's now possible to define a name containing "%s" in both section and group names when
using single file aggregation.
In that case, the services of files that don't belong to a group will be named
<SECTION NAME> <FILE NAME> and the services of grouped files
<SECTION NAME> <GROUP NAME> <FILE NAME>.
