Can I capture backup ssids in a workflow for cloning later?

I've been manually creating lists of ssids/cloneids by running mminfo queries after the fact, to use for nsrclone operations to clone from Data Domain to tape (LTO7).    A bit of a time sink since I have to make sure I get everything and not a lot extra, etc.   Currently running Networker 19.5.05.   

Is there any way to capture the list of ssids created by the backup in a workflow?   We just have one back up in a workflow, and sometimes a clone to cloudboost.   So the workflow process must make a list of ssids in the backup step for the clone stop to know what to clone.   And the post in this community, "Overview of Networker Group Cloning Operation", says as much:   "Every time a save job complete, it will writes the SSID into the file \\nsr\\tmp\\sg\\ \\<.groupName>. nsrclone job periodically checks on this file to get the cloning source.
The temp file will be deleted after the save group (workflow) completed"

Has anyone figured out how to capture the temp list of ssids for future use, after the workflow finishes?   Would make the tape cloning a lot easier, and if I can do this, then the tape cloning is more easily scriptable.    Would be great to have a scripting "hook" in the workflow... maybe there is a way for the policy completion command to copy the clone ssid temp file?  

Any ideas appreciated.
