Default pan/zoom/viewport for Maps in Workshop

I’m trying to cause a map to load in workshop on a given viewport on initial load. Setting the Default Value in the Definition tab of the string variable like so doesn’t seem to work.

I have a lot of objects plotted in my map, and I need something better than “start at world view zoom” (autozoom disabled) and show all of my plotted objects (autozoom enabled). Ideally, I can set the center point of where the map should be, and a zoom level. We have customers where their location matters most, the rest not so much.
