How to mix multiple textures by mask in shader graph?

Question

Unity

There is a texture mask with several colors. The colors are separated by a color mask. Now there are several bw (as I understand it) exits. Now I need to mix some texture into this output. Blend allows you to mix only 2 textures, I have all the textures go through a bunch of blends, with each new mask color their number increases, is there a way to do it easier?

Via shader graph—no way yet. It is better to write your own shader in this case.
By the way, you can see the compiled shader graph code and edit it as you like. I reset or limit the cycles in the shader this way, because they are too primitive in the shader graph.
