It sounds like what you may want to do is copy a zone from one zone to another, which can be done a couple of ways:
1. Hold down shift and select the objects/datasets and select "copy" from the side panel. 2. Select "Flow Actions" from the bottom right of the flow -> "Copy Subflow" -> choose items from the flow and select "Add" -> "Copy To".
If this is not the solution that you're looking for, would you please provide an example of what you would like the result to look like?
