Sorting Metadata Categories on Dashboard

I have several fields of metadata that are Multi-Answer Text Sets. I'd like to manually sort them on my reports. So, for example, I have generations (traditionalists, boomers, gen z, millennials, gen z), and I want them to appear on my Heat Map in historical order, not alphabetical.
The straight forward solution would be to simply add a prefix to each category (e.g., 1-traditional, 2-boomers, etc). I can't do that, however, because my metadata is part of an automated feed that can't be changed. I have the same problem with other metadata fields, like tenure.
Is there a way to manually sort my metadata on my dashboards?
