RRC 4.0.1

I am not sure if I am working at crossed purposes with Collections and Modules or not..

Scenario: We want to monitor change to artefacts overtime such that we easily a change report including the actual changes to artefacts.

Collections and Project Baselines seems to give us this. As new artefacts are created they need to added to the existing collection such that a subsequent baseline will enable us to see all the differences through the Collection Compare feature.

Modules comes close to this and benefits from not needing to perform a full Project Baseline, however there isn't a Module Compare feature (well not that I have found) so we can see the differences between baselines.

So it looks like Collections then.

Now, here's the issue with Collections and Filters:
From time to time we need to make sure we have all the artefacts needed in the actuall Collection, so an obvious way to do this is via filters to find those artefacts not in the Collection

However, under the Filter By Attribute section there is a "Where Used" option but this only allows for Modules even though the Collection is shown in the Where Used section of the artefact.

The Columns to Display only allows for "Used in Modules" to be displayed - not Collections.

So, whilst Collections seem to provide the best solution to monitoring change, they don't seem to provide a way to easily pick up those artefacts that aren't yet in the Collection but should be. Modules allow me to find which artefacts are in a module, or not. But I can't compare baselines of modules to track change.

Are my finding above accurate?
Have I missed something?
Am I going about the brief in the right way - that is to track change of artefacts between two points?

Thanks
