Would it be possible to extend this plugin to match on Ticket or ID, Summary OR user defined field? (as an override to Summary)
I am syncing two systems, and unfortunately trac is the slave. When I export from the Master system, I preserve the original system's ticket it into a custom field in trac. I would like to update based on that field, instead of Summary. I'd like to use "custom field" exactly the same way summary is used now, in this case, I would like to ignore the Summary duplicate checking and use my field. (yes, I have identical summaries on initial import for many tickets, gotta love "clone",sigh)
Logic becomes : if (ticket or ID)...else if (Custom field and Unique) else if (Summary and Unique) else....errors, or similar.
I may try to make this mod myself, but really like your plugin and don't want to kludge it!
