Ok...
For a work around maybe copy your basic preferred screenset to all 10 locations in your startup templates. Then hitting a number and you wont notice a change?
that will only "work" until you start to work with your project. each screenset will update based on what changes make when you work (show, hide, resize stuff, ...) now hitting a number by mistake gets a different screen which looks almost the same but not quite ... that'll be really confusing ... unless all screensets are locked (which would be really useless to start with)
either unbind the number keys or make some useful screensets (and label them like tracking, mix, editing, whatever) and start using them
