1. Getting Ready: Instead of dealing out the Special tasks directly, you can draft them. This means that all the players simultaneously choose 1 task to keep, and pass the rest to the player to their left. Then all players again choose 1 task to keep and pass the rest on. Continue until all the players have 5 tasks. Only then do you assign them to the Basic tasks.

You could also vary this format, for example, by picking 2 tasks during the first round of drafting, and 1 for each round after that.
