What's the easiest way to keep track of a bardic inspiration dice (that was given to you) on your D&D Beyond character sheet?

I don't see any features for it, what I've come up with is making a custom action, making the name something like: Bardic Inspiration (d8) and under Edit: set Activation Type to Action so I can see it. When you use it you can set Activation Type to "--" and it'll disappear from your sheet without erasing the custom action. Seems a bit clunky though.

Use the "Inspiration" mark next to your HP.  Your party's bard will tell you what the die size is.

That's for inspiration points given to you by the DM. It just gives you advantage.

That's theoretically what it's for, yes.  If your table uses it for that, then okay. 

Make an item called "Bardic Inspiration" with one charge.  Fill in that charge when you have it, clear it when you don't. 

I don't see an option for giving charges to anything...

Yurei’s telling you to “Create a homebrew Magic Item” called “Bardic Inspiration” and give it 1 charge.

I tried but didn't see the option, is it behind a pay-wall or am I just blind?

Edit: I found it, had to first create it, then go back in and edit "additional information"
