WestJet Rewards - Airmiles WestJet booking - stopover allowed?

Hi, not sure if this is the right place to post so my apologies in advance if it's not!

I would like to book a reward ticket through Airmiles (blue airmiles program) on WestJet. Just wondering if they allow stopovers on one reward ticket like you can do with Aeroplan? My itinerary would be YYZ-YWG-YEG-YYZ with 4 days spent in YWG.

TIA!

I think the answer is no. But you can book 3 seperate one ways.
