Adding "blank" to multiple value chooser list

[Anonymous]

Hi Rockstars,

Wondering if I can add in "blank" or "NULL" into a Multiple Value Chooser list. This would be helpful for building smartlists faster, rather than adding an additional "field is empty" filter and "or" function to perform the logic.

Thanks in advance!

Tried NULL but it does not work.

You may be able to use NULL, however, IS EMPTY/NOT EMPTY is a better filter choice to ensure the correct count.
