Currently one can decide to spefify the name of an PropertyKeyPath node or set an "any" selection.
So e.g. "prop.subprop" or "prop.*"
A feature idea is to allow partial wildcard (similar to wildcards in the comandline)
E.g. "prop.sub*" would match every property key with to parts where the second one starts with "sub".
Remark: If this feature is implemented, one most also take care of the template generation function to work correctly.
