RPE: RQM Reporting on Baseline or snapshot

Hello...

We are trying to use RPE (Rational Publishing Engine), and trying to generate a document accessing a certain testPlan, and going recursively to the TestCase and to the TestScript.

There is a nice article showing how to access baseline over DoorsNG, with Global Configuration:

https://jazz.net/blog/index.php/2017/06/23/generate-comparison-document-with-rational-publishing-engine/

But we don't use Global Configuration, and don't want to use it.

We are either using Project Baselines from RQM, or making a snapshot of the TestPlan.

How can we access a particular baseline from an RQM project over RPE ?

How can we access a particular snapshot from a TestPlan over RPE ?

(And still make the snapshot recursion over TestPlan->TestCase->TestScript ?)

Version: RQM v6.0.5 and RPE v6.0.5
