Quartus/FIR Filter/Avalon Streaming Interface/SOPC Builder

I have to build an FIR filter that is being used in a system that requires 2+ separate channels to be pumped through the same filter. I previously was using DSP Builder to build the FIR and I used an...

It seems like SOPC builder is overkill, and I could just mux the channels together using VHDL, but it makes me think I'm doing something wrong when the FIR filter has those avalon inputs.
