Is "blasphemy" really specific enough for confession?

Is "blasphemy" really specific enough for confession so that one could just say *"blasphemy 10 times"* etc.? I wouldn't think so but then I read in the *Summa Theologiae*, >"Properly speaking, the sin of blasphemy is not in this way divided into three species: since to affirm unfitting things, or to deny fitting things of God, differ merely as affirmation and negation. For this diversity does not cause distinct species of habits, since the falsehood of affirmations and negations is made known by the same knowledge, and it is the same ignorance which errs in either way, since negatives are proved by affirmatives, according to *Poster. i*, 25. Again to ascribe to creatures things that are proper to God, seems to amount to the same as affirming something unfitting of Him, since whatever is proper to God is God Himself: and to ascribe to a creature, that which is proper to God, is to assert that God is the same as a creature" (II-II.13.1.3) But you can also commit blasphemy against creatures such as the saints (see CCC 2148), so is this just for blasphemy against God?
