Sequence Last Step Field

We are looking to capture the last step completed in a sequence on a contact record. I have tried to use a workflow to help populate a custom text property on the contact, however, the issue is that Hubspot does not treat “Sequence Activities” like normal Activities. It doesn’t look like Hubspot allows anyone to reference “Sequence Activities” in workflows. But based on the last sequence step, we would like to automate addtional processes and workflows, but we are stuck. How can I access “Sequence Activities” in workflows…
