How to set the total number of concurrent threads for a single vertex?

In a cluster composed of 100 jet instances, a vertex of my pipeline needs 5 threads for parallel processing. How to set it?
The distributed method of sourcebuilder sets the parallelism of each jet instance, which is at least 1, that is, it becomes 100 threads

The Pipeline API currently doesn't support setting total parallelism. This reflects the fact that, on the low level, Jet always creates the same number of tasklets on every node. So there is no easy way to do this at the moment.

OK, I'm looking forward to setting the total number of concurrent vertices in the next version
