How do you modify existing ViPR SRM Reports to exclude specific data?

I hav a question regarding "report creation" that I hope someone can answer.

I would like to recreate a standard report that is already in ViPR SRM, but remove some of the arrays the report captures.

For example: the Usable Trend Capacity graph. It covers 8 VNX arrays, but I'd only like to show 5 of those VNX arrays in the graph.
