Yes please! Generally speaking it would be great to have more functionality in that area and I'd refer to Turbo Integrator in TM1. I'm sure many will be able to relate to that.
Definitely see this as a positive improvement to the management of processes. Any process that has multiple steps and that needs to have a slightly different version of means having to create from scratch leading to the opportunity to make mistakes.
I would love to see this ability. It will be useful when I need to debug the process by being able to create a duplicate process, edit it to contain actions that can be run in one go, and then debug the remaining actions one by one.
