Overriding the amount of extra entries instantiated by a Gtk ListView (default is 200)

I’m working with a Gtk ListView and Gtk ListStore and I’ve found that it binds an excessive amount of entries on first load, which causes memory and performance issues in my app. At first, I thought it was binding all entries, but according to comments on this GTK issue, ListView defaults to instantiating 200 extra items in order to facilitate scrolling, which I’ve been able to confirm with further testing. Is there any way to override this number? In the case of my app, I need a much smaller number (perhaps 10 or 20). Any help would be greatly appreciated.
