Cart events on quantity updates

Hello, thank you for your great plugin. Unless I have applied wrong settings, I have noticed what follows in cart events:

When quantity is increased, an “add to cart” event is pushed to GTM.
When quantity is decreades, a “remove from cart” event is pushed to GTM.

These behaviours increase the actual number of add to / remove from cart real events. I wonder if they could be treated as “update_cart” events, or – even more precisely – “item_quantity_increased” / “item_quantity_decreased” or something similar.

Thanks!
