Is there a way to globally adjust the options I've set into a portal filter?

 

I have a bunch of individual portals using initial rows 1-15+ and sometimes I need to adjust a variable to accommodate future enhancements, etc... I'd rather update 1 field and set the portal to that 1 field, so if a change is made, it will cascade the updated information to all portals using that same variable. Going back to edit all of them 1 by 1 isnt' fun. If possible, what is a good approach? Thank you!

It depends on how much of the filtering expression you want to parametrize this way. At the very extreme, you could set it to something like =

Evaluate ( Preferences::FilteringFormula )

Works perfect, thank you!
