In building out workflows that have With Items, sometimes I want to do something with each item in the list and I have to create that, then back out and create a sub workflow, relink that to the main workflow and set the parameters. It would be much nicer if I could just create a With Items action and then right click - Convert to Subworkflow

Alternatively some way to create a subworkflow from the workflow screen as opposed to opening a new tab or backing out of the current workflow. Something like being able to right click on a blank space and create a subworkflow.
