Saving orbital elements in MPC format?
Pressing S on the orbital elements+observations screen saves the orbital elements in this format:

Is it/would it be possible to save this information in the one-line MPC orbit format instead?
A use case for this would be being able to import these orbits into Stellarium via its Solar System Editor plugin:
@void4 The orbital elements from the fit are available in the mpc_fmt.txt file in the .find_orb directory in your home directory
