WDG - change behaviour of filter isnull

I am using 21.2

When i filter rows and select Is Null, it doesnt return any rows.  I think it is due

to the underlying bounddatafield is blank, not null.

I would like to give users ability to filter rows with blank values, so I can either

add a new filter type or change behaviour of existing is null filter.

Im not sure how to do this ?

I did find javascript to hide the values, but not to modify or add new ones

thanks in advance
