Gradual Slider Return


I’ve recently purchased Djay Pro for my mac. in the past i have used other Djing softwares, a feature that i found really useful on these softwares was a gradual slider return, in particular for the tempo slider. When i have synced one song to another and then want to return that song to the original tempo, i was able to click an icon by the slider causing it to gradually return back to its original tempo. Is this currently possible to do on Djay Pro? if so how do i do it? if not could this be a feature request?
