How to share one action to multiple UUT test?

Hi,

In fact, I don't know how to define the topic exactly.

My request is like the following :

For example, I have a signal generator and four UUTs.

Signal Pattern 1 ON -> batch(4 UUT test...) -> Signal Pattern 1 OFF, Signal Pattern 2 ON -> Batch(4 UUT test...) ...so on...

I got stuck how to put the action into the teststand and do once instead of 4 times.

Something similar to the callback of  ProcessSetup, PreBatch, and PreUUTLoop,

but I wonder if there is a way to call an action once within multiple UUTs in the MainSequence.

Could someone give me some suggestion? Thanks a lot!
