Aappointment Slots: How to make an item available again?

Hello - We've been using the appointment slots widget based on your suggestion, thank you!  However, a client had to change their time and now they are booked for two spots.  How do I make their old time available again for booking?Thank you so much!Erica-------------------------------------Erica Haller Photography LLC609.903.2001www.ericahallerphotography.comFacebook.com/ericahallerstudio

The workaround is to add one more slot to the item. For example, change Monday{1} to Monday{2} to have one more slot activated for the Monday item.
