Based on the positive response to the shopping closure tag question I recently asked, I think the best way to handle this would be to edit the "cannot be generalized" tag to incorporate this specifically.
I would propose to change the text of the tag as follows:
Questions that cannot be generalized to apply to others in similar situations are off-topic. In particular, "shopping" questions asking about recommendations for specific programs or universities are off-topic. For assistance in writing questions that can apply to multiple people facing similar situations, see: What kinds of questions are too localized?
