I have multiple Sources in a ProcessFlow that create tokens with different labels on them.
Eventually in the process, those tokens are Batched (Groupby one of the labels).
That works well BUT the resulting token only contains the labels from the left input of the Batch.
Is there a way to automatically create (on the outgoing token) the labels that were on the token from the right input of the Batch as well as the left?
I'm not taking about aggregation as I don't want to do a calculation. I just want to have all the labels from the incoming tokens on the outgoing token.
Is that possible?
