spell?

i find with this site it is too restrictive with adding spells? is there a way to add spells as I've got a lot of spells but i can't add them all? 

You're going to need to be more specific about what exactly you're trying to do for anyone to provide any help.

I hope I'm correct in assuming you want to add home-brew spells. If so, this guide may help. https://www.youtube.com/watch?v=FaIzhzStM-8

On the other hand, if you're trying to prepare more spells than your class currently allows, then this guide may help. https://www.youtube.com/watch?v=9d0CGR5pG1I
