Not that I’m aware of. Instead of using Locators to specify the export range I use a Cycle Marker that I’ve cleverly named “export range” in my Templates. Since it is dedicated to exporting audio it doesn’t get moved around for any other Tasks.
What a great workaround! I haven’t made much use of marker tracks, beyond a single one I use to bookmark different parts of my project. I’ll look this up— thanks for sharing this solution!
