How can I automatically show mass in kg and LBS on my drawing?

I can insert a property link and have the mass show on my drawing.  I currently have it set to kg.  I also want another section to show that mass in LBS.  Currently, I have to remember to do the math and update the property in the summary information manually.

Is there a way for SW to automatically update a summary information field with data from another property?

Thanks,

brian
