This is very odd. I'm editing that quantity selector again and while some things change, the simple name of "Select Quantity" refuses to change. Is that another proper that is being "pushed" through? It's rather frustrating as I can't tell what I can and cannot change, even though their are options for everything

.
There is no way to override this, to select a predefined quantity, or at least an upper limit absolute?
Or perhaps, what about creating a custom button that forces a certain sell quantity, is that possible, no matter what the quantity, or at least forces an upper limit somehow?
