Walgreens stacking spend boosters?

I've heard that you can stack a digital and paper spend booster before..

However, can you stack 2 digital ones? I have a $5 back for spending $20 as well as $7 for doing 2 $10 purchases. I've previously done one $10 purchase, so I was was wondering if my next $20 purchase will trigger both of these boosters, or just one.

Thank you!
