Please Help: Magnetic Course Display in OpenCPN

[Stargazer1942]

I am a new member of this forum and I new user of OpenCPN. I have been a sailor for more than 35 years and done charting and routing on numerous software programs and paper charts before these wonderful things existed. And if this is an overly used or abused subject matter, I apologize in advance for bringing up again. I cannot understand why a program of this power and sophistication does not display courses in either True or Magnetic format at the user's choice. I have done searches on this subject matter in this forum and on the Internet and I am now at the point of going in circles. I hope this is not because I am getting too old and no longer understand proper searching techniques. Please, is there a way of displaying the courses created in OpenCPN in Magnetic as well as in True.

I thank you for any help you can give me.
