I don’t believe this is possible already, but as is true with most things in Touch, could def be built.
I think the path forwards would be to figure out what format you want to export to, or if that format is not open, find out what software you want to export to, and determine what open formats they support for import.
Then, you’d need to write a script that searches your container or network, looks for geo COMP’s, shaders, builds a database of their parameters and inputs, then writes that info out to the format of your choosing.
Def not a simple task, but maybe doable with some time!
