I had some thought of doing something like that last fall when I was three- and four-tabling a bunch of accounts on my own - setting up an alternative front end that supported mutlitabling and automatically populated battles with the last team you used for that ruleset/daily, so you could change them if you wanted to but if not just hit go.

Like a lot of things that got hung up on me being 20 years behind on web programming and kind of dreading trying to catch up. The nice thing about Ottermaker and Herons is that they're all back end, although they'll probably evolve out of that eventually.
