Hello HubSpot community!
My name is Dylan, I’m a member of the HubSpot product team. I wanted to let you all know that this is currently possible, as mentioned in this post.
Here is a HubSpot Product blog post we made at launch and a Knowledge Base article that explains how to use the feature. As a previous commenter mentioned, this is currently available for enterprise accounts only.
Thank you all for your continued feedback - it helps us build a better product!
