Duplicate a template Session

We would like to set up a template session that has the format we would like all our techs to use when adding a new customer session in RDM. This way we can standardize everything to all look the same. What I mean by this is we have a "parent" folder for the customer name, and beneath that sub-folders that will organize all of the devices by type.
Right now if I select "Duplicate Entry" it will only copy the main session name.
Please take a look at the doc I've attached on how we set up our sessions and sub sessions. It would be great if there's a way to copy all this rather that having to manually create each folder every time we add a new customer.
Is there a way to Copy a Session, with all it's sub-folders now?
Please let me know if this makes sense.

Thank you,
Roberta Day
