Modify Playlists with >50 Items

I'm working on a custom playlist consisting of all of Star Wars in in-universe chronological order so I can watch it like a sane(?) person. This has been quite a painstaking activity because it bounces back and forth and all around town between various shows and movies. Everything was going swimmingly until I realized there were a few metadata alignment problems with some Stream Links. I fixed the metadata, but now the wrong episodes are in a few locations. As such, I wanted to manually modify those ones out and pull new ones in, but they are beyond the first 50 that the Web UI will display:

The last time this was discussed a workaround was suggested, but this is an entirely different use case that would not fit with that. As such, I'd like the ability to see more, even if it just within a page of 50 and then you can shove the top one back a page and the bottom one forward a page and work from there. Otherwise, I'm rather stuck on this project for the time being and will have to stick to the spreadsheet for reference.
