When starting up a new game it would be nice if I could have a few presets between the Competitor screen that I could pick from.

Sometimes I want to use a set of specific Competitors in a single player game, and other times I would want to use another set, or a random set. 

Here is a design of what I am thinking of

Niceee! Improving the personas is always in our radar :P

Or random by difficulty level

Check this idea then, it seems to be right up your alley.
