FP 8 should remember old settings after changing groups

When I select chael 10 - 17 within group All for example and then I change to Bus to work with busses (or using any other group button) and then go back again to All my FP 8 always starts with chael 1 - 8 again. It would be great if FP8 would "remember" the old setting and set it again. Now I always have to go to chael 10 - 17 again manually.
