Ability to Select multiple dimension members in a single column/row in SmartView Ad-Hoc Reporting

When creating a SmartView Ad-hoc report.

When we choose members from a dimension right now, we are only able to push them across columns / down rows , but we want to place them in one cell on the PAGE and run an ad-hoc report for the combination chosen.

It would be really helpful if someone was able to achieve this and share their insights.

Thanks!
