Command Line switch to open to a bookmark

I would like to open a pdf to a bookmark. I can open to a specific page using "/A page=x" in the command line. The documents I am opening from a command line all have the same chapter structure and the chapter titles are saved as bookmarks, but the starting location of each chapter changes depending on the length of preceding sections, so opening to a speicifc page is not working, but opening to a bookmark would.   

This works for opening to a specific page: 

C:\Program Files\Adobe\Acrobat DC\Acrobat\Acrobat.exe /A "page=4" "Q:\SOP\SOP_1474.pdf"

I need something like this, but "bookmark=" isn't the correct argument

C:\Program Files\Adobe\Acrobat DC\Acrobat\Acrobat.exe /A "bookmark=Technical " "Q:\SOP\SOP_1474.pdf" "Q:\SOP\SOP_1474.pdf"
