Easy way to handle custom checkboxes on mobile?

What I’m trying to do

I’m trying to use Obsidian for a digital bullet journal and would like to use custom checkboxes to help. Unfortunately, adding the relevant type in source mode is a pain, so I was hoping there’d be a plugin that streamlines this, much the same way that Callout Manager does for callouts, for example.

Things I have tried

I searched the forums and the reddit but didn’t really find what I was looking for. I was hoping someone might have a suggestion!
