Advanced Link and Fetch Pipeline Video

I am not able to find a video the demonstrates the linking and fetching feature beyond this intro to the feature: https://university.quickbase.com/build-powerful-pipelines-using-included-features/645783

The video I am looking for included instructions for including these additional features and I cannot find it 
-Bi-directional updates ( i.e. A would update B and B would update A)
-Linking existing records

Thanks!
