Importing Morphtargets

if you export a mesh with morphtargets from another application, you usualy got every morphtarget in a seperate mesh.
Is there a way to import those meshes as shapekeys somehow?
Or is there a script that moves the vertices of one mesh , to match a second mesh?
Any other ideas maybe?

Just found out that there is already a script within Blender which dose exacly what i asked for. Scripts>Mesh>Rvk1 to Rvk2.
