Is there a way to easily use alternate capstones for classes?

[Senko]

I'm just wondering is there an easy way to select alternate capstones for classes e.g selecting well prepared for a wizard?

At 20th level, the wizard has a spell for every occasion he can imagine—and a few he can’t. The wizard gains two additional cantrips per day, six additional 1st- and 2nd-level spell slots, four additional 3rd- and 4th-level spell slots, two additional 5th-level spell slots, and one additional 6th-level spell slot.
