Learning initiative for new staff only

Content

Hi

Does anyone know how to set a learning initiative for joining staff only?

We have a report analysis called 'All staff' and we have previously used this for our mandatory courses.  We have a course which is being made mandatory for all staff however groups of people have already completed the learning, and some are in progress.  I can assign to the rest of the staff by uploading a person number list, but we then want it to auto-assign to anyone joining.

I realise we can add an initiative but we can't leave the 'Initial Due Date Option' blank, so that means that anyone who has already completed will get another completed assignment, and anyone with an incomplete assignment will be withdrawn and re-added.  It does work, but will get very messy with reporting and is not what we want.
