Yes, but centering is awkward as there is no way line it up exactly without knowing the width of the dropdown. So you can make a menu like that, but it would need to be a static menu, ie: if you add another menu item to the dropdown (or slider as those are know as) the dropdown/slider would not be centered correctly.
The Horizontal slider menu option is available for our premium subscribers (https://geek.hellyer.kiwi/premium_support), but they do not center at all for the reason above.
