Glossary with all 26 letters on a page

Can’t really share a link so I hope my text words are enough…

I have the letters at the top A through Z and then all the terms and definitions below. Clicking on a letter will take you to the first term that starts with that letter.

I was going to do this with sections and have the collection for definitions in each section and the filter is set for each letter but alas the english language has 26 letters and needs 26 sections. The limit of collections per page is 20, so I’m hitting that limit. I had tried doing a nested reference but the limit is only 5 and some of the letters have 6-10 terms that need to be shown.

Is this out of scope for collections and something I should do by hand for each definition?
