The ability to be able to quickly make the same comment within multiple tasks by either applying a template comment or even adding a shortcut where you have a list of commonly used comments that you can add easily.

For example:

Where there is the / Commands have one which is a template comment so you can go into a task and type /C (or something like that) and then a list of your pre-saved comments come up and you can just click which one you want to add

This is a common feature in ChatBot services where there is a button or you press / and a list of common replies pop up. (I attached an image of this below)

I think this would be a really handy feature for when you are making the same comments on multiple tasks
