Load multiple IIR coefficients from one txt file?

Hi,

Sorry I ask so many questions recently!

The author of REW software is adding a feature request to allow the room correction filter coefficients to be exported in a text file with compatible formatting (i.e. none) for Sigma Studio.

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?
