Is it possible to create a learning Analysis that is triggered by #of days past a certain date?

Summary:

Please, we're trying to understand if there is a capability with learning assignments (possibly via an OTBI analysis) to trigger certain learning based on an employee's hire date. For example, training that is assigned on the date of hire, then again at 30 days, and again at 90 days. I've never done something like this before and haven't seen any obvious ways to do it within manual or dynamic learning assignments. If this is through an OTBI analysis, can someone share how to accomplish this and how it would look tied to a learning assignment.
