This can currently be accomplished. In each camera’s settings, under Event Recording, you can turn off Notifications for only that camera. Similarly, in the settings for each sensor, you can enable notifications for that sensor. After setting these as desired, make sure you have the global notifications for the account enabled (no slash through bell icon on home page).
To be able to automate these, more actions need to be added to the Shortcuts feature. You can vote for that at the topic below. Be sure to click the VOTE button at the top:
