no, that is one of the biggest shortcoming cura is facing at the moment: the lack of differentiated speeds. daid decided that for simplicity (which is really good in the beginning if you just want to get something printed), that one speed for everything is fine. after months of printing, and slicing, the requirements change, and more complex print jobs require more different speeds.
One of the big problems with Skeinforge is that I cannot get it to differ between sparse and full infill. So infill speed will adjust both.
In the good news department, I'm working on realtime-tuning, where you can adjust the speed of moves/perimeter/loops and infill independently during printing, without affecting the rest.
