Question: Can I forbid SemiAlgebraic to use RootOf and demand a special output of solutions?

Hey guys, 

I try to solve big systems of polynomial equations and inequalities. Therefore I use the command SemiAlgebraic. In the moment I take those result and want to go on calculating with them. Sadly it turns out, that solve has some problems with RootOf expressions. It doesnt find a solution (althoug the graph shows that there is one) and gives the warning solution may have been lost. So now I though I might just aks SemiAlgebraic to give me solutions without RootOf expressions. For example you can write {x = RootOf(_Z^2 - y)+1, 1 < y, y < 2} as {x=t+1, y=t^2,1<t<2^0.5 . This might be easier to work with for solve. 

So my question is: Is there any way I can tell SemiAlgebraic precisely in what form the solution should be? 
Since the websites are down Im not able to do a first own research on this problem. So thank you in advance.

Felix
