Sorting Order gets disrupted when Swap dimension feature is in use

The "Swap" functionality of the pyramid Analytics is a great feature from a user perspective, but it has some flaws.

Say, I have a chart showcasing the Sales against the "Sub-Category" dimension, and it is currently sorted in descending order based on the Sales value. The moment I use the "Swap" feature, to replace the "Sub-Category" dimension using the "Country" dimension, the sorting order no longer gets retained. Basically what I want is that, even if I swap the dimension, my chart should still be sorted based on the Sales value in decreasing order.
