This question may well belong in the 'excessively fiddly and not generally requested' basket, but I dare to ask because with Directory Opus, all sorts of amazing things are possible.

I want to sort the files in a particular folder first on the extension (column heading 'Ext', not 'Type'), secondly on the filename. _But_ I don't want the extension-sort performed either in alphabetical order or in reverse-alphabetical order, because each such sort places often-used files on the second screen of the 100-file folder.

Specifically, I want the extension-groups sorted in the order:  
pdf, txt, tex, dvi, log, ptp  
(and then the files within each extension group sorted alphabetically).

Is it possible to sort the extension groups by such a custom order?
