A motion which requests consideration for the first time of additional circumstances is one which may be designated more properly as filed under Rule 60 (b). . . . However, where it is not clear whether a particular motion should be considered appropriately under Rule 59 (e) or 60 (b), consistent with the liberal construction policies of these rules, the motion should generally be considered under Rule 59 (e), if timely filed.
