make rollup suites better

[#1]

Currently, rollup suites have virtually no analysis functionalities. Can this be changed so that they perform like normal report suites?

ClientCare told me:

Your understanding is correct “Data contained in Rollup report suites does not support subrelations, segment” this statement is still valid. Here’s a help doc that speaks about it:

https://docs.adobe.com/content/help/en/analytics/admin/manage-report-suites/rollup-report-suite.html

Also, Rollup Suite is not-available in Analysis Workspace. Refer the help doc:

Just wondered if there was a reason why you wouldn't put all you data into one report suite and use virtual report suites to split back out? Is it a performance thing or something else?
