• Documentation change/addition

Description

It's incredibly niche, but it'd make my life a lot easier.
This allows a task to return a Replacement Trigger, allowing tasks to dynamically adjust themselves based on load or external influences.

This definitely needs to get documented somewhere, but that's for the docs branch.

Changes

• Checks the return type of tasks, and if it's a Trigger, replace the existing one.

Checklist

• I've formatted my code with Black
• I've ensured my code works on Python 3.10.x
• I've tested my code

This is targeting master. Are you sure that's what you wanted?

[silasary]

It is not. But I can't retarget in the mobile app
