Assignment Work by Resource Report - Data Table

Hi --

Due to an internal requirement I have part replicated the SSRS EPM Assignment Work by Resource Report (the main histogram). However I am now required to replicate the Data Table which sits below ths report.

I have added a Matrix and re-used the same dataset which feeds the main histogram, however I am struggling to get it to display my data correctly. In the left vertical column I'd like it the same as the default report i.e.

Resource
Availibilty
Capacity

And then Months across the Top.

However, I have Resource, and then my Allocated Availibilty and Alocated Capacity appear in columns side by side - how do I configure so that they appear under the Resource?:

Also - Is there a way to expand the "Architect" by default?

Thanks!
