Hello crystalbyrdfarmer,
Yes, it’s possible, but you need to create a new Members directory, see
https://dontdream.it/bp-profile-search/custom-directories/
for the necessary details.
In short, create a new empty page and insert a shortcode like this:
[bps_directory order_by='field_2, field_31']
where you specify the list of fields you wish to add to the Members directory Order By drop-down.
Please note that, at this moment, this only works if you use the Legacy template pack.
