how get spot channel color data

To get  spot  channel color data (su as c=100 m =20 y=0 k=0)  as the foreground color....because The following process needs the foreground color,I want to simplify the operation process too, My files often have 8 spot channel and 8 layers , All spot channels color data is cmyk .

process :
