Are you referring to the jtreg usage? ie

jtreg -jdk:xxx -v -r reportdir :compact1

The group is not an option it is a test designator similar to doing:

jtreg -jdk:xxx -v -r reportdir runtime/NMT gc/

Adding this is trivial. The "template" would be:

jprt =

There doesn't seem much point in me adding that at this time though. 
Better to leave it until we know how it needs to be defined.
