Set a filter expression on a plan based on a specific "Implements Requirement Collection"

I'm using RRC to create collections of requirements. One per Target Release.

This collections are then linked to a Product Backlog Plan

Product Backlog Plan > Tab Link

Implements Requirement Collection

      > 1007: Target MP 1.0

      > 1230: Target MP 2.0

I have created a connected Work Item for every requirement of those collections

Now I would like to create a view containing only  Work Items from MP 1.0

I was able to filter only on "ImplementsRequirement;set"  but not on one of the specific collection.

Has somebody an idea if and how I could do that 

Thanks erwin
