External scripts thresholds via hobbit-clients.cfg

I have looked thru the mail archive and don't think this has been asked? I think the answer is no but will ask just to make sure...

I have a common external script on a few hundred systems and would like to be able to control the thresholds via the hobbit-clients.cfg file as I do with the out-of-the-box tests. I don't want to have to change the thresholds by editing each system individually. Is this possible?

Thanks
