How do I set multiple values for a user preference of String Type

I'm creating a macro to set certain system settings. I want to set multiple paths for File Locations>Document Templates. The problem I have is that I can only get one path. I've got 2 lines of code that specify each path as follows, but I only get the last one.

boolstatus = swApp.SetUserPreferenceStringValue(swUserPreferenceStringValue_e.swFileLocationsDocumentTemplates, "c:\Path1") '

boolstatus = swApp.SetUserPreferenceStringValue(swUserPreferenceStringValue_e.swFileLocationsDocumentTemplates, "C:Path2")

I want to be able to set multiple paths for this setting. How do I do that?

Thanks,

Craig
