Hello @Andreas_P
I don’t think we have such thing available in HubSpot workflows but the connection can be made easily.
What we can do is create another new workflow which will be continuation of the present one. And then in each branch of Yes/No, you can enroll the contact to the new workflow. Doing this, all your contacts from any of the branch will be enrolled to newly created workflow and there you can do the rest of the process.
Thanks
