Position to Position dotted line relationship

Hi all -

My client is planning on using dotted line relationships, but position to position rather than position to org unit. The manuals for Nakisa 3.0 seem to imply that possibly the dotted position boxes only show up if it is to the org unit. Is this correct? If so, is it difficult to customize to also have them show for position to position dotted relationships?

Thanks!
