Changing a specific value across multiple parameters and across multiple Revit categories

Hi, is there a way to find and replace a particular parameter value ( for example a dash) with either a string or a blank which is used on multiple parameters applied with multiple Revit categories? I know how to look based on a single parameter but not sure if this can be done to all project/shared parameters at once? For example, replace all dashes belonging to any object and parameter with a blank or a string such as “Not Applicable” and vice-versa.

Many thanks!
