When I have different classification hierarchies set up across multiple report suites, there is no way of seeing which report suites are not matching (you just get the message "The classifications for this report do not match for all report suites. Only classifications that match exactly can be viewed and edited across report suites.")
It would be great to
1) See which Report Suites are not matching (similar to the way this is handled in the "Conversion Variables" set up
2) Copy hierarchies from one Template to another (similar to the way this is handled by the menu structure options).
Lastly, it would be good to be able to copy the actual values of a SAINT over from one report suite to another
