I don't think FindFirst and FindNext has that capability. I would use the
AllMasks constant and then manually match using a simple regex that caters
for all variations you need. Yes, FindNext will initially match every
file, but doesn't the underlying system have to look at every file anyway
to only return a specific mask?

Just for your reference, the simple masks syntax.

   ?  matches a single character
   *  matches multiple characters

With regex you have MUCH greater control over how to match something. For
example, here is a simple regex to match the mask you listed above. I
don't know how strict you want the ??? text so I used a . (any character
exect \n), but you might want to tone that down a bit.

   t(?:.{3}|s.{6})\.sel
