Do you mean...after you transform them once, you transform them again from that position? If so, you can''t.

Vertices are only transformed by the matrix specified by SetTransform() before they are rendered by the fixed-function pipeline. They are not transformed right after SetTransform() is called.

Can''t you just multiply the matrices together, then apply the transform?

No i mean when you use the customvertex format and specify D3DFVF_XYZRHW. Which makes the vertex coordinates screen coordinates. So im wondering if there is anyway to use transformation matrices on rhw vertices.
I want to do this because im doing 2d in d3d. I know i could rotate and move etc manually, but using matrices would be cooler i figured
