Sigma Studio Question


I have asked the author of REW software to add a feature for the room correction filter coefficients to be exported in a text file with compatible formatting (i.e. none) for Sigma Studio.

However I want to confirm, must every bi-quad be in a separate file for loading to each cascaded 2nd-order filter individually, or is there a way to load multiple 2nd-order coefficients from a single file in one hit?

I note it is possible to load multiple coefficients in the 2nd-order index selectable module (and get a really nice graphical display), but I don't believe they can all be applied at the same time, is that right?
Nevermind, I found it myself, just a right-click after growing the algorithm. :)
