[Feature Request] Add Option to Display Total Count in Box Headers (e.g., Reports Excluded Box)

I suggest adding the ability to display a total count in the main header of boxes that contain a list of reasons or sub-categories.
For example, instead of 
```
Reports excluded:
Reason 1 (n = xx)
Reason 2 (n= xx)
```

Add the ability to 
```
Reports excluded (n=xx):
Reason 1 (n = xx)
Reason 2 (n= xx)
```
