DSP BUILDER - Pin Assignment

Thanks for youre reply, but that wasn't my question. I wanted to know if it's possible to assign blocked pins (blocked by quartus as programming pin) directly in DSP Builder?

In my design there are three blocked pins I must assign, but when I start the compiler, DSP Builder tells me that it is not possible to use these pins. So I have to compile my design first with DSP Builder, reload it in Quartus, assign the pins and compile the whole design in Quartus again.

This takes a lot of time (approx. 2h) which I want to reduce
