I'd be inclined to believe that there are likely to be controls to prevent people not authorized by higher ups within the NSA from doing this, as that would represent a security problem.
I am, to put it mildly, considerably less sure that these controls operate in a manner that inhibit NSA leadership from directing that this be done in specific cases, when they feel that providing this kind of under-the-table feed of information, particularly to domestic law-enforcement when the conditions in which the information was gathered would, if it were known, prevent the use of any information derived from it in court under the fruit of the poisonous tree doctrine.
