Question regarding in store rewards and the limitations

I would like to use my points to help pay for GTA VI when it comes out, but I keep seeing conflicting things about auto-issued rewards and point rewards limits so I thought I'd ask here.

In November, I'd like to use my $5 monthly pro reward, then redeem my points for a $10, $15 and $25 reward to take $55 off the cost of the game. Would that type of reward stacking be allowed?
