You can, you just need to do it at the original time of booking. Can't add it retroactively.
My one way flight was $39. Economy bundle is $69, Premium bundle is $79, Business bundle is $114. I'm seeing $49 flights have $10 increases to each bundle, and $59 flights having $20 increases to each bundle, so it seems like the bundle price is standardized to whatever the base fare is.
