[Feature Request] Append text to the end of the discription

[showierdata9978]

Is your feature request related to a problem? Please describe your use case.
I would like to add documentation to our auth handler (a decorator) without overriding the original description, but just append onto it

Describe the solution you'd like
Add a method to append text to the end of the description
