Multiple Timeline states
There may be more glamorous ways, but the very simplest way is probably to have two identical objects, one with the animation, and one without, both with an initial state of Hidden.
Triggers:
"Change state of [Object with Animation] to Normal when timeline on this slide starts if variable [HomeVisited] = false else change state of [Object without Animation] to Normal."
"Adjust variable [HomeVisited] set = true when animation [opening animation on object] completed"
If you are talking about a slide transition, and not an animation on a single object, it's the same. Set the slide the way you want it, then duplicate it and remove the transition on the second. The first time, jump to the one with the transition, and every other time, jump to the one without.
