Will do; would be great to fix (or at least understand) the alignment before I do though, for completeness. :-)

I've added this to the wiki now, since having tested it out I don't think my alignment problems were anything to do with the issue at hand. To fix the alignment, I have now defined: \def\GenPagecommand#1{\hfill\llap{#1}} and said: pagecommand=\GenPagecommand for every setuplist except those which require prefixes. This allows me to have very large page numbers and long prefixes without seeing the page number alignment go all squiggly. The appendices now have: \def\AppPrefix#1{\GenPagecommand{A#1}} and: pagecommand=\AppPrefix in the setuplist, and the backmatter is done similarly. Possibly this leaves me exposed if a very long title runs over into the llap, but I'm hoping not to run into that. Is this the only solution here? Thanks again. Duncan
