If I understand correctly, this might be accomplished with Nesting.
Add each 'recent' clip to it's own sequence. Then nest those sequences into a 'bumper' sequence and edit them as if they were clips. Finally nest the 'bumper' sequence into a 'weekly' sequence at the end.
Set up this way, you can change the clips in the 'recent' sequences, and those changes will be reflected wherever those sequences are nested.
Really appreciate your speedy reply, thank you so much! I'm watching the AdobeTV video on nesting sequences & it seems like this is precisely what I am looking for.
Thanks for teaching me something new & helping me save a lot of time going forward!
