Is it possible to link the end point of a line to a layer

Hey there,

I'm wanting to link the end point of a given line path (created with a shape layer) to the center of a precomped image wherein if I move one of the images, the end point of the line attached to the image moves with it without readjusting the start point.

Here is a picture of my current composition, if it helps. I'd like to link the line that goes from the Ashwaganda text to the Ashwagandha picture, where in the endpoint of the of line is at the center of the Ashwaganda picture.

Thank you!
