Is there a simple method in the modern Thunkable X to have a stored dictionary of key-value pairs that allows you to change a key’s value, save it and only Initialize it once?

You can use the [object blocks](https://docs.thunkable.com/blocks/blocks/objects) for that.

If you want to save it across app sessions and have the data persist, then use the object block with a stored variable. Otherwise you can just use an app variable.
