Combine company and contact list

Creating this for a customer (:
Would love to have the ability to combine company and contact list
For example:
(1) Ability to pull associated contacts from company lists into contact list

(2) It would be possible if “List membership” is a selectable option within contact/company properties itself.
Currently, this has to be done manually which is super tedious.
Thank you!

Yes! HubSpot Team PLEASE add this capability. Thank you!

Upvoted! This would be very useful.

This should be easy to implement and would be an improvement for many users. All that is needed is an assignment based on the ID - we currently do this manually with SVerweis in Excel. Please implement it!
