Please provide multiple levels of sort

The new "Custom Fields" datasets have been introduced as EA/beta.

I have two custom fields that I want to track and report on: APC UPS model name and serial number
I want to have a table of Company, Site, Endpoint, Model name, and Serial number (sorted by the first 4 fields).
None of the offered designs in BG seem to be able to accommodate that construct.

The "list" gauge only has one sort field, so I can get the list sorted by Company, but not the rest.  As a result the data view is extremely skewed with information appearing out of order.

Please provide multiple levels of sort!
