How do I combine or merge similar master commodities?

I have commodities "Miscellaneous Scrp" and "Misc-Scrap".  I want to combine these two.  How do I do that?

Answer

As of November 8, 2016, this is no way to merge commodities in the system. We plan to add this merge functionality in the future. For now, I suggest disabling one of the master commodities. Once the functinality is added, you can merge them then.
