'02 Liberty Radio Question

I just bought a 2002 Jeep Liberty, it has the factory AM/FM CD/Cassette combo. I know if u push the preset station buttons 1-5 a second time you get stations 6-10. I have figured out how to set stations 1-5 but can not figure out for the life of me how to set stations 6-10? I do not have an owners manual and couldn't find any info online. Someone please help because I have to many stations I want to pre-set and can't fit them all in the first 5 alone.
