sql reporting

If I could get just one thing in the next relase I would ask that the attributes that are collected in application manager for sql server all have historical reporting. . .
While the data being collected is good I only get a limited nunber that can be reported on. We host over 20 sql servers that are prone to performance issue's. The company needs this data to help trend our db over time. We feel limted not being able to trend using appman and have several sql dba's that have been using other tools to get the data we need.

The shame is that most of those attributes we need historical data are being collected in application manager with no way to access the historical data using the web front end . . .

Please let me know if this is road mapped, and if so how long we can expect to wait?

Thanks
