Unlikely. "Gauging the spacing" on things like this is largely irrelevant. You'll always have exactly as much space as you need. There aren't really "empty slots" or spaces to fill. It's just an interface for the game to display how many of those things you've activated. Much like the Key Item inventory [which quite often here gets called out for being a "big open empty space! Let us use it for other things!"], it's not actually a defined inventory, it uses space as needed.
