I'm working with a relatively simple table with columns for room number, name, and dietary restrictions. Dietary restrictions will be a dropdown multi-select column.
| Room | Name | Restrictions |
| 1 | John | Halal, Diabetic |
| 2 | Sally | Halal |
| 3 | Jane | Halal, Diabetic |
| 4 | Mike | |
| 5 | Kim | Halal, Diabetic, No Pork |
What I'm hoping to achieve is a count of the unique values, so in my example above:
Halal, Diabetic 2
Halal 1
Halal, Diabetic, No Pork 1
None 1
Can I do this?
