I have 49 timelines in an on-going project, and was looking for the same thing. I found a tip that can do this, in the YouTube link below. Basically, you select all your timelines, right-click > Create Timeline from Selected. Then you render out that timeline as Individual Clips and use Source Names.
While it does automate the job, I lost out on Data Burn-ins for Source Clip name, so pick your poison.
Bottom line, I'm all in for this feature request. Blackmagic, please make setting up batches easier, without having to resort to workarounds like these.
