Yep, you can just change your order script (the script on your website that generates keys after an order goes through) to generate 2 activations per product key.
Increase Default Activations
bkeeneyswIt's pretty typical that our customers want to use our software on a desktop computer and their laptop. I know we can manually go in and change the Activations Allowed from 1 to whatever.
Is there a way to set it two automatically so that all product keys have a default of 2?
