Hi Robert
Using reports from the newest version will be unsupported. You may try getting importing only this report but it risks to become a problem, since the report contains also dependencies such as input controls and resource bundles. Any changes could be a problem for the report or the other OOTB reports. You could create a new report with a different id and using the same jrxml but again, this could lead to issues. We have changed some of the security, so latest PPM patches have some of those fixes, but it's hard to say if everything will go well or not.
I think the best recommendation would be to wait for the report to be officially included. I will check with our Product Management to see if this can be backported for you.
Thanks -Nika
