Nope - just add up the distances of the flight segments. Great Circle mapper is handy.

And then make your itin fit the 5 stopovers, 2 transits, 2 open jaws rule.

(need to use atleast 2 carriers if no cx/ka..and 3 carriers is cx/ka is included - do compare with a standard asiamiles award..that might work better if its a short or medium hal and/or coach class redemption)
