include function file in verilog-AMS

In a library I have a few cells for which I have created verilogams views. I am performing similar functions in the various verilogams files. So I included all those functions in a separate file. Here is a snapshot of the file wreal_func.txt (this is just an example to explain what I want exactly)

/////// file start

function real mult;
  input real a,b;
  mult = a*b;
endfunction

function real divi;
  input real a,b;
  divi = a/b;
endfunction

/////// file end

Now in my modules I have used these functions(like for example  assign z=divi(x,y);  )

If I include the file in each module like

module example();

`include "/somepath/wreal_func.txt"
//some code

endmodule

then it works properly.

Is there a way to include this file globally during simulation(like an ADE option) so that I need not include it in each and every module. That too I need to include the file inside each module. If I define it outside a module(similar to constants.vams) it again throws a syntax error.
