That would definitely require a script. The approach depends on exactly how you want the script to operate and the characteristics of your sequence files. If the sequences are all the same lenth, it could be as simple as creating a “template” comp that has all 600 sequences (with video disabled) and the logo. The script would create 600 duplicates, enabling a different sequence each time and placing them all in the render queue.
Or, a more complex script could load the sequences into the project window, build comps of the correct length, bring in the sequence and the logo, and drop it in the render queue.
Not particularly difficult, but not a project I would recommend starting with if you’ve never done any scripting.
