Data Soft Clip module ADAU 1466 & 1467

Hello, friends!
I am developing guitar amplifiers based on ADAU 1466 & 1467. There is a problem using clipping in the Data Soft Clip module, it has a very small clipping adjustment range. There is no such problem in the Data Hard Clip module, the adjustment range is not limited in it, and this is very good. Can I expand the adjustment range in the Data Soft Clip?
Is there a tool for developing custom modules in Sigma Studio for ADAU 1466 & 1467?
