passing parameters to simulink from base workspace

Hello Everybody,

I am trying to pass variables from Matlab base Workspace to
Simulink Blocks, for that i am using assignin, evalin and
sim commands. With all this i m able to pass variables to
all the simulink blocks except signal builder.

For the signal builder to update the signal for any change
made in the base workspace, i need to go to
Signal menu->Customize Signal-> Then enter variable name
mannually.

So my question is: Is there any way to update the signals in
Signal Builder automatically whenever there occures change
in the base workspace of the matlab.

Kindly help me ... It is very urgent requirement for me..
Thanks in Advance,
