Moving to specific point in animation

Is it possible to pose an animated character or object at a specific point in a specified animation. For example, say I wanted a characterfrozen halfway through the ‘walk’ animation (but I don’t want to animate through the walk cycle to get to that point)? I know I can create poses and import those, but for one project I’m working on, I need to be able to put characters in poses based on random points along an existing animation

TIA
