custom filter parameter EMPTY/NOT EMPTY

Hi,

I have rows with certain fields empty. However I sort my table it will always start with many rows having empty cells (not all cells but th important ones).

Is there a way to use custom filters to allow to only show rows where a certain field is NOT EMPTY?

My rows are INSTAGRAM, NAME, BIRTHDATE for example.
I often have either the instagram name, or the birthdate or the name, sometimes I havew all of them. I would like to have the table start sorted by NAME but then the first pages show an empty NAME column because many rows don’t have a name. If I could offer a filter to blend out all rows where NAME is EMPTY/NULL, the table would start with names from A-Z.

I have not found a solution to this, yet.
