When I give players a custom item, then when it grants a spell (maybe a cantrip or something like that), I usually have to input the item, then manually add the spell. They are connected. EDIT (because I'm dum dum): I'm mostly talking about D&D 2024. My suggestion: When creating the item, the modifier list should have a 'Spells' option where you can select spells from your Compendium instead of manually putting everything in. Also, on a sidenote item windows should be able to be enlarged when modifying them.
