I would like to define an advanced filter within my pivot table that allows me to look at diagnosis codes, or at procedure codes - but I do not want to hard code values within the pivot table definition (get the %OR defined).

I would like to be able to allow my dashboard user to chose what specific diagnosis codes or procedure codes they are interested in. So for example one user may want to look for # of patients with cancer dx or patients who have had a radiation procedure.

How can I accomplish this OR feature using dashboard filters?
