share and edit title lists

We wish to share  title selection lists that one of us have started up, so that another two people can edit the same list, by adding and removing titles from it.

I have looked at your online help, but can only locate shared editing access for a clients page, not titles lists created, like this one.

Can it be done and if so how?

It’s just like us sharing our work within IMDb Pro with each other on one link ( or more of course) – we are all members  IMDb Pro.
