null values in date slicers

[joe_m_lischynsk]

Date Slicers - Allow for Null values in the 'Between' function. Have a checkbox to ask whether or not to "Include NULLs?" in the BETWEEN function. (example: to show all records where the CLOSE DATE is in the last quarter, OR where the CLOSE DATE is still NULL).

Yes! We really need this. Seems like a no-brainer to me.
