I suppose.  A plausible actual regex would be

   _ta(-[0-9a-z]{4}){1,12}

which might be a bit dense.  That's not quite right because the
numbers in the label have to be sorted, but there's no way to say that
in a regex other than enumerating them which would be bulky.

Whatever you do, please put include some text reminding people that it's
a conceptual glob stype wildcard, not a DNS wildcard.

R's,
John
