I'm going to be playing an intelligence-based bard and I'm wondering if there is any way to make it so that the uses of bardic inspiration reflect this (like the boxes that you can check off under features and traits). Does anyone know if you can make an item or subclass do this? 

If you add a Granted feature named “Bardic Inspiration” to your subclass, then it should overwrite the preexisting feature on your character sheet. However, it won’t actually happen until your character takes that subclass at 3rd level.
