In case anyone needs this information in the future, the solution was to set the TransitionIn animation to Hidden, then the DataChangeIn needs two animations. It doesn't matter what the first animation is (as long as it's not Hidden or something), but the second animation needs to be one with the "Reverse" checkbox. I don't have vMix in front of me, so hopefully I'm getting all the names correct. Set the delay to however long you want to the title to be visible *plus* the transition time for the first animation and check the "Reverse" box. Now when the data is updated it should animate in, hold, then animate out as long as the title is set as an active overlay.
