Did you find a workaround? If not, please consider adding a new idea to the Ideas section of the Tableau Community. Most of the new feature ideas for the product come from the community created ideas here.
Both views use a dual axis - one for the bars, and one using text marks for the label. To position the labels in the top view I edited the text shelf and added a newline with a space so the text marks "cheat up" a little bit. In the top view the measure for the text marks is SUM(Sales) + 10000 so the marks are positioned a little higher, then I turned off tooltips for that mark.

Hah brilliant! The only thing is, I'm on a map. But I'll give it a try, and either way will definitely make use of this in the future. Thank you!
Hi Jon, you can still get the same effect with a dual axis map:
Note that I had to play with the label configuration (there are two newlines with spaces set to 5pt size in this case to get the margin to look right) and the history fade setting (to prevent the first mark from getting too light to read). Also note the overlapping marks in this case in NY because there were two marks both in NY. Dealing with that to prevent overlap would require a lot of additional calculations.
