Job templates

I have a number of jobs that do exactly the same build except for 1 param to mvn changing - the test group to be run.
In all other respects the jobs are identical.

I would like to define the job once and just use the definition N times just providing the parameter for the test group.

I know I can clone the job to create a similar one, but when I want to change some param like adding new Artifact definition I need to do it repeatedly for each and every job in the stage.
It is also quite easy to get things messed up, like running "group-2" both in "Group 2" and "Group 4" due to small mistake in clicking.
