Animating a line to appear from one end of a mesh to the other

Hi!

I am looking to animate either a straight or wavy line to appear from one end of my mesh to another (almost like ketchup being squirted onto a hot dog). How would I go about this? I am using sequencer to create a small video clip of this action.

I am new to using Unreal and animation in general, so hopefully this isn’t too difficult to achieve!
