Electronic survey seal signature etc TBC

Has anyone found a good way to get the survey seal into Trimble Business Center. We have several simple jobs that we have really no need to export to another cad software. How do we get my LS seal and signature digitally in. I think in civil3d they scan or make a block or something. Out of my knowledge realm. But i have a small job i am wrapping up and was hoping i could bypass exporting everything to cad and just finish it up in TBC. But we want to make sure we protect the LS. It will be exported to a pdf.
