Make List Membership a property to Export or Copy to a new Property

Hi
I am working across multiple clients’ Hubspot, and they all work in lists for their sales team in terms of acquiring new leads. But i would like to get some dynamic reporting based on how far they are on each list in terms of their initial sales process, using some form of ‘List Membership’ property for a company.
I’ve had a lengthy and very helpful support process with a Hubspot Employee but sadly we concluded that this was not possible.

Thus some way to extract the information in List Membership on a Company or Contact into a property, maybe an “Only-Hubspot-editable” Multiple Checkbox or a Single Line Text, something like that.

This is crucial, and I hope everyone can take this seriously. If we can make list membership a multi-select property, it would solve a lot of issues.

Upvote here! This is essential to know if a contact is a member of multiple lists to avoid duplicate marketing emails being sent. Drilling down into each contact to see the list membership(s) is not viable.
