Help With TTB Formula Approval for a Blended Whiskey

[derek.duf]

Looking for advice since I get a different answer from every different person I talk to from TTB.  We bottle a blended whiskey of Rye and Bourbon and have had the formula and label approved from some time.  We wanted to bottle that same blend that we transferred to a red wine barrel to finish aging.  TTB would not let me label it as a blended whiskey, only as a distilled specialty spirit, and in turn I cannot use the word 'Whiskey' on it.  Well that doesn't make any sense to me, I see plenty of whiskeys that are finished in various barrels.  Any advice on where I'm supposed to go from here?

Yeah its DSS, we had that with our port finished bourbon. You'd set the formula spirit type as "Blended Whiskey finished in Wine Cask" or whatever you want it to say on the label.
