Can Simple Filters Pick Up Null Responses

Good Morning! I am finalizing a dash that I would like end users to be able to filter by several dimensions. The problem is that the N count changes when filters are added to the page - even when each filter is set to show 'All' responses. I believe this is because (1) Each filter excludes Null values when applied, even when set to show 'All' ; (2) Page filters function additively, meaning that only records that have a response for all filter-questions will display. Unfortunately, there are hundreds of responses for which no response was offered for at least one of the filter-questions.
Is there any way to have filters include null responses when 'All' is selected? Because the filters are intended to be manipulated by end users, I don't think Advanced filters are a viable option here.

Thanks for your help!
