PLD - new condition

It would be great if a condition for user 'status' could be added. We have users in our courses that have:

*awaiting start


We are looking to have a 'Welcome to your course' PLD set up.

Students are added to their courses with an 'awaiting start' status from our student management system (SMS) and we want to send the email when their status changes to 'active' which could be months later. The timing of the change from 'awaiting start' to 'active' is managed from the SMS and could be different for different users.

I can see many other uses for a condition = user status
