This is a planned feature for Jess version 7, now on the drawing
board. Until then, you can try using fact inheritance to factor out
the common parts of your templates.

(deftemplate two-slotted-thing (slot a) (slot b))
(deftemplate thing1 extends two-slotted-thing)
(deftemplate thing2 extends two-slotted-thing)

(defrule do-something
(two-slotted-thing (a 1) (b 2)) 
 =>
)

This rule would fire for both thing1 and thing2 facts.
