Extending checklist functionality


I need to have an estimate in minutes/hours in each checklist item.
Is it possible to create a powerup to extend the checklist funcionality or do I need to create a tasks powerup from scratch to have my own checklist items with the added funcionality?

Thank you!

Your best bet is going to be making a Power-Up that draws/manages its own checklist items and their data. There isn’t a clean way to keep extra data about checklist items alongside the checklist items. The checklist items really only support the normal REST methods to add/update them.
