Using Row Selection in Analysis Web Item & Filter Command

In the 7.0 WAD (Web Application Designer), I have two analysis items that both have different data providers, DP_1 & DP_2. The two data providers are views from the same query.

In the properties of the first analysis item (DP_1), I'm using the Row Selection - 'Single with Commands', and I want to have a command that will filter on the value of the characteristic in the row selected and transfer that filter to the second analysis itme (DP_2). Is this possible?
