Does not appear to be one, but a PR would be welcome to add one!
I am not sure if that will actually be easy to add though (as the single-ended slider does not have a notion of 'end' yet or a thumb). The way we achieve this functionality in the subplot tool is to have two sliders (one for the top and one for the bottom) with linked callbacks.
