Option to manual log/override Fitbit sleep data

Not all Fitbit/Apple Watch etc users wear their devices every night to bed. If syncing with google health app, it would be nice to have option to manually log hours slept within the same goal. If you choose the option to sync when setting a sleep goal there is no chance to manually log hours later unless you create a separate goal which is obviously redundant. Also sometimes the device isn’t secured correctly and shifts in middle of night giving inaccurate data. It would be nice to be able to correct it when it happens.
