Not possible at this time. The chores are stored in a json file, but I wouldn’t recommend trying to edit them manually. Currently the only way to add/edit chores is via the integration configuration or via services. The service access gives you extensive capability to build out import and export type functionality, but you would need an engine for it to handle that syncronization or load. This is the approach @realrkennedy is working on for their personal needs.
The next step in the progression of this app will likely need to be custom dashboard cards that will give that more refined experience you’re asking about with quick add/edit/duplicate, but there is quite a bit to building it properly to match all the different input validations, language translations, etc. You can see a few posts above where I’ve done some experimenting with good success. On the bright side, the backend system was built to handle these kinds of features going forward it just a matter of now needing to build out some key frontend ui capabilities.
