Use file name to adjust document settings

I have a document that is used for filling out FEMA flood certificates. Part of the document is set up so that when we use the address as the file name appended with -CD , -UC , or -FC it ignores anything after the dash and fills in the box for the street address. Is it possible to adjust this so that the address still completes and have the part after the - activate a radio button that changes fields that are calculated and read only to uncalculated fields that require a number to be entered.
