Need an app to paste stuff based on categories/needs

So, I'm looking for an app that will allow me to paste items that I "bank" based on categories, such as:

• Email
  • to:
    • option 1
    • option 2
    • etc.
  • cc:
    • option 1
    • option 2
    • etc.
  • subject line:
    • option 1
    • option 2
    • etc.
• CLI Commands
  • command 1
  • command 2
  • etc.
• "Canned" Chat Messages
  • message 1
  • message 2
  • etc.

Ideally, I'd like the app to also be able to preserve clipboard data precisely somehow (e.g., rich text, image, etc.).

Is there something out there like this, that exists? If so, where? I've tried Flycut but it's garbage tbh.
