Can Randomize() function select different random values for 2-3 different registers having same constraint range?

How can I make sure that when randomize() is called, different values are selected for all these similar 4 registers. I want that they never get the same random value everytime randomize() is called.

constraint range { 
reg1 inside { [0:31] };
reg2 inside { [0:31] };
reg3 inside { [0:31] };
reg4 inside { [0:31] }; }
