Can a motion to amend a judgment to specify that it is without prejudice pursuant to Rule 60?

3 In Sack v. Low, supra, 478 F.2d at 362-63 n. 1, we allowed a judgment to be amended to specify that it was without prejudice pursuant to Rule 60. We carefully noted, however, that ordinarily such a motion would have to be made under Rule 59, and only the "unusual circumstances" of that case allowed for a departure from this requirement. Id. We see no such evidence of unique or special circumstances in the present action.
