> We would still want to run #1 and #2 synchronously and #3 and #4 asynchronously? Is that possible?

We plan to add direct support for “block start call until workflow unblocks it” feature. In the meantime the simplest workaround is:

1. Execute workflow synchronously waiting for it to complete
2. Workflow executes #1 & #2
3. Workflow starts a child workflow in [disconnected mode](https://community.temporal.io/t/best-way-to-create-an-async-child-workflow/114/2).
4. Workflow completes unblocking the original thread that started it
5. The child workflow executes #3 & #4 in the background
