Execute sub-workflows in parallel

The idea is:

Hi, I’ve searched a lot in community about this feature, execute sub-workflows in parallel like this topic(Running subworkflows in parallel). Do your guys have plan to support this feature? Thanks!

Are you willing to work on this?

I don’t have any idea about working on this feature.

I think this would be a good usecase for this requested feature:
