Multiple inputs (merged) ?

Hi,

I wonder if it's possible to merge multiple inputs on the same processor, kind of like Breakaway DJ did? Like, I'd like to listen from my Breakaway Pipeline and from the input of my soundcard at the same time, merge the signal on the same processor and of course output it on the same output? I know I can use some software to listen from the soundcard input and play it on the pipeline, that'd work but it'd also increase the latency on the soundcard input. So would it be possible to have multiple inputs to listen from for each processor?
