Modify playlist view to add additional field?

I want to use the stream playlist view to curate a community training video series that we have been hosting for our new PMO. We have monthly training calls that we record, but we also want to make the link to the PPT slides visible within a playlist format. I was hoping there might be a way to modify the view of a playlist in a similar fashion to editing other MS List views but I can't seem to figure it out. 

Ideally wanted to be able to show a button in the sidebar thing. See my janky mockup image for what I'm describing
