[issue34458] No way to alternate options

I agree that a custom Action subclass like this is the way to go.

The regular 'append' is implemented in _AppendAction class, which is different from the default _StoreAction.  So even if there was enough demand for this new idea to be put into development, it would be implemented as subclass (along with a registry entry).
