SOPC Builder: Component Editor Question

I have develop a peripherial in verilog that uses parameters. Some of these parameter are strings. The SOPC Builder componenet editor only allows integers as a parameter value. I though I could ignore this until I went to compile the design. It turns out that when sopc builder generates the code for the module, it sets the string parameters to 0. Which screws up the intended function of the design.

My Question: Can I modify the ptf file so that the string value is put into the parameter and not 0 when the system is generated?

Thanks
