Hey Jody, Thanks for the suggestion here - I think you're right, and it turns out the plugin is already using this, but it just isn't splitting on multiple date formats (it's just ingesting it all as a string). So, I think that will work - I will just split the incoming string on the logical or, and add valid date formats to this property descriptor's user mapping (as it already was doing), but now with multiple valid date formats instead of just the one. So, same idea, but using the architecture already available, sounds great. :)
