Needs: we need in the same Customer Journey to add "if conditions" based on entity fields and add actions to update data inside entities.

Currently we can do the following :

1) Real time: we have "If conditions" based on data from entities, BUT CANNOT update field entities with workflow or flow as an action.
2) Classic Customer Journey: We CANNOT add if conditions based on contact entity, BUT WE CAN add a workflow to update data.

It was a requirement from a big customer who asked us for that, and I think its very important to have these 2 features in the same customer journey.
