Max number of patterns/chains in song mode?

So I’m building my set on an analog rytm and it seems like ive hit the max amount of allowed patterns in the song mode. I have 8 really long chains that are each different songs and each use a memory bank. Can anyone tell my if I can increase that amount? Or am I doomed to rebuild my set using less patterns and more muting techniques?
Please let me know of any help you can give. thanks

EDIT: Realized I can just create a new song. Sorry, been up all night making a new beat. My heads spinning from 140 bpm. Still kinda curious tho… Its less button pushing to keep the chains in the same song.
