Hi kwebber,
Since this is your first post in the Community, I'd like to give you a warm welcome.
At this time, QuickBooks Online doesn't offer the ability to set up employee reminders for their probationary period. I encourage you set up reminders on other sources such as a smartphone or on your computer. I know how having this feature would be useful to you and I encourage you to send feedback about this to our engineers using the Gear icon and looking for Feedback. New product ideas and improvements are based on the feedback we get from users like you.
Let me know if you have other questions. I'll be here.
