copy text in brackets to margins?

Is it possible, while doing the conversion, to get Calibre to make a copy of the line numbers, and place these numbers in the margins. So to best approximation in text editor we might get something like this:

[1083b1] the blah blah blah blah blah blah blah blah blah blah


Thanks in advance!
