If you log meal counts, the only way to enter them in bulk is through the Instructor App on a Class-by-Class basis. The Instructor App can be accessed through Enrollsy.com or https://app.enrollsy.com/instructor. (This is not an Admin group action as of the writing of this article).
Any Admin can create an Instructor Account to do this. You can learn how in this support article. Once you create an Instructor account, login at app.enrollsy.com/instructor and follow these steps:
Step 1 - Filter by Date
From the Instructor App, first, choose the Class, then filter by date:
Step 2 - Adjust Time
If needed, change the time. Click the "Now" button to choose a different time:
Step 3 - Select Enrollees
Select the Enrollees by checking the boxes beside their names or choose "Select All" to select all Enrollees in that Class.
Step 4 - Choose an Activity
Click "Lunch" (or whatever your meal Activity is), and you're done!
