No, I don't think you're missing anything.
There is that "PRO" interface that requires you to install Adobe Air...which is something I, for some reason, don't want to do on my new PC.
But I've used the "PRO" wagering pad before...it was a long time ago though...you might want to check it out? Might be better for those types of wagers...pretty sure conditional wagering isn't available on that one either...but maybe I'll boot up my old PC just to test it out again.
Oh the crap we have to put up with...
First world problems.
