I don't want to make cusom list containing all items in the list. Is there a
way using two cumston lists in one sort - i.e. fruit and color...and have
result as below...

grape
cherry
melon
apple_red
apple_green
apple_yellow
pear_red
pear_green
pear_yellow
tomato_red
tomato_green
tomato_yellow

Please help and thanks!
