Redmine

This is, I apologize, a very ignorant request for support. I'd very much like to modify the redmine_serial_number_field developed by Matsukei to work with the DMS custom field types. I had thought, with quite limited knowledge alas, that it might be a relatively easy modification and that I might find a reference to "Issues" that might be easily changed to or amended with "DMS" and that it would just work and "Automatic Serial Number" would appear at the top of the "Format" menu drop-down list.

Sadly, such a simple answer does not seem to be the case. If there's an easy answer or an accessible reference, I'd very much appreciate any pointers.

Thanks,

-David
