Unless there's a different NPC specifically named 'Retainer Consignor' that's hiding somewhere, no I can't.

For the record, both my Retainers are stationed in Limsa. They're both on a venture right now, so is it possible the option dosn't exist on the menu unless one of them is inactive?

For the American English localization, it's the Retainer Vocate you talk to. There's one in Limsa, Ul'dah, Gridania, Foundation, and Kugane in the market districts.

Steps are:
Use Retainer Fantasia.
Make certain the retainer is not on any venture.
Unequip all gear from the retainer you wish to change.
Talk to the Retainer Vocate and select "Change a retainer's appearance and nickname" (this option only appears after you have used the Retainer Fantasia).
Select the retainer you wish to change.

The usual Character Creation screen is then displayed to choose appearance and voice. Once that's done you're asked to select personality and nickname.
