importing state space models to simulink

Hello! I am working on a matlab project now, and I will shortly need to start building blocks in a simulink model. My question is very simple, is there a way to import a state space model (saved in the current forlder, or available in the workspace) directly into a simulink model without having to copy and paste all the matrixes (A B C and D) into the silly GUI simulink wants one to use? I need to move over some very large ss models and I really want to avoid all the hassle of copy-pasting. I would be very grateful for any advice.

A=[-2 1;-3 0];
B=[0;1]
C=[1 0]
D=0
set_param('untitled/State-Space','A','A','B','B','C','C','D','D') 
% untitled is the name of your simulink model, 
%State-Space is the name of your State space block

Thanks Azzi, this works a treat! Now on to my other Simulink issues :/
