Preset instrument only first time on parallel test

Hi,

I have a parallel test with three threads that do not startsimultaneously, I need that execute a preset of the instruments only the first time.

I tried to create a Rendezvous on the first thread for execute a preset instruments and other threads if they are existing jump it.

Are there other alternatives or this might be fine?

I use a TestStand 2014.

Thank you
