SIMPLE QUESTION, BROWNIE POINTS FOR ANSWERERS: changing the file path used for an audio recording

After changing the name of an audio recording in the .band Media folder, the .band file continues to use the previous file name to try to find the audio file. I want to update the file path so that it uses the same file but with the new name. I thought I might be able to change the file path by editing projectData, but it appears to be encoded.

This is a common, crucial feature present in virtually all DAWs. Surely there must be a feasible way to do this in GarageBand?
