ADAU145x SigmaStudio: Pass Input Parameters, script

Suppose there are a few constants that need to be passed to a Sigma Studio project (the equivalent of command line parameters in C), is there a way to do it in SigmaStudio. For example a user would like to set the Gain Value to a value at the start or choose between multiple filters at the beginning. Is there are way to do this in the schematic or the H/w configuration window.

Is there any detailed document on SigmaStudio scripting apart from sigmastudio_scripting.pdf be used for the same.

Thanks
