How to overlay a pdf file (such as a blueprint) over a orthophoto or mesh

I work with a lot of general contractors who don't have microstation or any other Bentley products besides ContextCapture.  We want to be able to overlay a pdf file, such as a sheet of the blueprints, over an orthophoto or mesh.  Is there a workflow in ContextCapture or ContextCapture Editor for this?

Thanks,

Joe
