Booking Scheduling

Hi all,

I'm hoping someone can offer me some advice. I will be actively setting up a page for my customers to book sessions in. Each customer will need to book two separate slots, however, I need to enforce a 2 day lag in between the two slots. Is this possible? I've had customers book both their slots for their same day, which has caused issues. I need a 2 day window in between to allow for testing. How can I make sure the system forces a customer to leave 2 days in between their slots? I've looked the scheduling policy section but I'm not clear if this is an option. 

Hope this makes sense.

Best,

Dan
