Best Practices - List Syncing

We don’t have a “sync List A in Dynamics to List in HubSpot” where you’ll automatically have a static or dynamic list created.
What you could do is “tag” the contacts in a list and use that as a criteria for rebuilding your list in either system.
What’s the use case for needing lists transferred between systems? Are you taking segmentation in Dynamics and using it for marketing campaigns in HubSpot?
