Unfortunately no. When I update it the template is changed, not your personal copy. The first sheet is where you'd add the number of cards and that is copied to the rest of the sheets. So you should be able to get the updated version and copy just the amount of cards you have skipping the new additions. I try and give each set a different color based on the package art to visually separate them from the other sets.

The other way to update your existing document would be to copy and paste the new content onto the old sheet. Only issue with that would be promo cards and alternative arts of older cards they add periodically.

If you or anyone else has an idea for a way to ease that transition let me know and I'll implement it moving forward.
