Annotations Layers across scan dates

I’m attempting to create polyline features marking existing irrigation lines. The lines were visible on the initial map from several months ago but are now more difficult to see with new landscaping. I would like to be able to see the lines I’ve marked out from the initial map displayed on the current map where they are not easily visible.

I can export the polylines as a DXF and import them to the current date model but they do not carry the labels and are a fixed file. Is there any way to carry the annotations over to different model dates in the same site?
