hi @Matthias Queitsch -- this is not currently possible, but one question is if you see a significant difference between that behavior and a potential alternative behavior of "wait for all upstream in-progress runs to complete". There are scenarios where these would lead to different results, but we've heard users interested in both behaviors. We're actively looking into expanding the scope of options for these policies and this sort of usecase is one of the more popular ones we're looking to support.
