Title. Also re-echoing #1637 . If you want to re-DM me that quick how-to of how I fork the proper part of TMW so I could add it for you, then also remind me how to then make a merge request for you, I'd be happy to. If I notice any other missing things, I'll either post a ticket or do it myself.

Done. You can do this by hitting the edit (pencil) button on https://github.com/ascott18/TellMeWhen/blob/master/Components/Core/Spells/Equivalencies.lua. Github should guide you through it from there.
