Storing pictures in the track comments box

I have bought myself a rather lovely Behringer Neutron, and it works very nicely with Ardour.

However, as it is completely analogue, and doesn’t have the ability to store patches, it would be really nice to be able to take a photograph of the knob positions and upload it to the comments field.

NB: A similar request appears to have been posted in 2011: Pictures >> comment feature
