This is a feature request, unless there is already a way to achieve it.
I’m aware that we can use “Split based on event attribute values” only for campaigns triggered by events. However, it would be great to have something similar in any kind of campaign. Let me explain.
I can add a “Wait until” block where the condition is based on an event being performed (with or without specific attributes).

I would like to then be able to split based on the previously awaited event attributes:

I managed to simulate this pattern by creating one segment for every combination of event and event “value” attribute but this is cumbersome and also slow during execution.
It would be great to have something directly doable in a single workflow.
Thanks in advance!
