The scheduling wait list can be accessed under the Scheduling menu of your EMR (Scheduling > Scheduling Wait list).
This should bring up a list of any existing wait list events. You can filter this using the provider drop-down menu or sort by clicking on a header (Date Added, Preferred Date, or Priority).
Each event in your wait list has three actions: add, modify, or delete. The add option (green + icon) will bring up the usual scheduling window with pre-populated details from your wait list event. Once you add this to your schedule, it will automatically be removed from the wait list.
To add a new event to the wait list, click on the plus icon in the upper-right corner of this window. This will bring up a window that looks very similar to when you are adding a real event to your schedule with additional fields for "Priority" and "Remove from Wait list On".
