Is it is possible you could add an "Export as IMDB list" function? There's scripts to import IMDB lists onto IMDB after exporting them from IMDB. Example of what it looks like:
1,tt8880894,2023-11-16,2023-11-16,,Living with Yourself,https://www.imdb.com/title/tt8880894/,tvSeries,7.2,26,2019,"Comedy, Drama, Sci-Fi",34673,2019-10-18,,,

I tested. You can remove most of that data, so:
This still works.
So you'd only need to copy and paste the IMDB link and ID with all the commas. The site only reads the "tt2234222" ID at the start. If the IMDB link provided by Coollector doesn't exist anymore, it just stalls on the line - so it also might be a useful way to find dead links.
