This is a multi-material blend node that offers both an opacity mask and a blending mode for every layer. It allows for up to eight inputs to be blended into a single output.
This can be a heavy node, but if your concern is keeping your graph neat it can be a great tool.
Version 2: Updated to the latest version of Substance Designer (currently 2019.3), and tweaked a few of the input labels. Note that the sbsar version does not allow for setting blending modes, only opacity (this appears to be a program limitation), which is why I've included the sbs version.

- Opacity (for each input)
