I imagine this can be done in Calibre already, but I'm not seeing how to do it, so maybe someone can enlighten me.

Is there a way, during a bulk metadata edit, to set fields from more than one match? IE, put \1 into series, \2 into series_index, and \3 into title? If not directly, any ideas on how to approach doing so? (I'm a perl programmer; using regexes to extract data is second nature. I just don't see how to get it from the captures to the fields easily)
