Yes you can!

Just head over to your Redemptions menu, and click on Redeem via ACH:

Then find underneath your original bank account where it says "Add New Bank" and click it.
   Next you will need to Agree with our terms and conditions with enrolling your bank account:
   Then you will find your bank in the menu, or if you don't see it listed, type in the name of your institution. Once you select your bank, it will then ask you to login to your banking institution so that we can add it to your profile.  No need to manually input your routing/account info.
   Moving forward, you will be able to select which account you want to do your ACH redemption on. Make sure you pick the right account, other wise you will need to cancel the redemption and wait for your balance to be updated before you will be able to redeem to the right account. Keep in mind, you can only cancel an ACH redemption if it's in a pending state.
