Auto Fill the Subscription agreement box in one page checkout

[butanedragon]

Hi! Our store recently switched to the one-page checkout (not good) and we've noticed the express checkouts don't work as well as they did on multi-page checkout. 

If you try to use express checkout it usually fails because the subscription agreement box is way down at the bottom and you have to opt-in to successfully pay.

Is there a way to setup the checkout link to have this button auto filled(selected with checkmark)? So the customer doesn't have to scroll down to the bottom to select the checkbox

Any assistance is appreciated! Didn't have this issue on multi page checkout and of course we can't go back, per Shopify support
