[CS:GO] Freeze animation at specific frame
 

I created a prop_dynamic entity with item_healthcharger model (models/props_combine/health_charger001.mdl).

The model has an animation "idle". When the animation is played, the blue marker is slowly shifted from right to left. I need to set the marker position to the middle and freeze the animation, how can I do that?
