Try look at my reply here using the layer node.
You work EXACTLY like photoshop, including the stacking from bottom up.
No need to a multi sub material.
You could also "Shift+Drag" your bitmap to create a copy of your diffuse map, set that copies RGB Output to "Alpha as Gray" and the Alpha Source to "Image Alpha"
