'Wait for condition' in Workflows

Currently workflows (scheduled, webhooks, manual) don't have an option way to have a step wait for a condition to be true, it's pretty much all asynchronous as far as I'm aware.

But often we need to wait for condition to be true in order to move to the next step but we don't have this option.

Example:

webhook data comes in and is written to columns and then a Call API needs to use data from one of those columns. Currently there is no way to make the Call API wait for that data.

Solution doesn't need to specifically be "wait for condition", just something like that to make certain steps in a workflow synchronous.
