You could put the reused part from your save event into a function in the component, pass down a save event from the LiveView to the component. In the LV’s event, call the common function of the component and then implement the custom logic for that LV. At the moment the event is on the client with some common logic followed by the custom handler of the LV - invert the relationship.
Not sure if it’s the most elegant solution but I did something like that yesterday when migrating to Surface.
