rendering a multrack rehearsal session - script?

[ampere]

Hi
I just recorded our latest band rehearsal and I am left with about 10 tracks, each 2h long. I have created markers for each song which helps a lot. In order to render single songs, I select the marker and press 'A' to place the in/out markers at the beginning and end of the song and finally render only the marked region. So far so good! It would be nice if there were a 'render marker' command that would do the same steps as described above and would also take the markers name
as a filename. I wonder if I can use some scrippting to that. Additionally , it would be even better if I could do a 'render all markers' sort of command. Any ideas?
thanks
