Is there a way to add comments in md5 file?

I have a library of files. Each file has each own *.md5 file (created by Total Commander) with md5 hash and additional *.txt file with some comments.

Is there any way to move these comments from *.txt file to *.md5 file (and delete *.txt file) in a form of some internal block of comments (like using "rem" in Windows batch files or "<! --" and "-- >" in HTML) so I could still use *.md5 files to check the hashes?

Any line beginning with ; in .md5 files is a comment.
