Beatles -
Just keep trying. I do shops for them every month, and I also do not have a self-assign ability.
Also, what may help - take some of those "hard-to-fill" locations that may require a longer drive. With gas prices up, they may not get filled, but if you OCCASIONALLY (heck, not all the time, just occasionally now.. LOL) let them know you would be willing to pick up a shop - it may help your chances.
(I read another thread where schedulers will warm up to those folks who do go out of the way, and some schedulers will even help you put together a route).
