New Midi-Interface: Do I have to rework all my songs?

so I have a certain USB-Midi interface for my hardware synthesizer and a ton of songs with Midi instruments which are configured to use that certain USB-Midi interface as Midi output device. If I just want to use a different USB-Midi interface, it seems like I have to reconfigure every Midi instrument in every song. Isn’t there a way to avoid this? Is there something like a virtual Midi output device that is mapped to a physical Midi output device?
