Yes."Objective" and "subjective" are sometimes used to describe both the functions themselves, and where they were used. I was trying specifically to understand how they shaped directing and informing communications in the eight three letter groups (STJ, SFP, etc) that Keirsey had identified. So I began paralleling things up along the line of subjective and objective. (I had thought that "directing" communications, such as S and T together might have had to do with "objectivity". Turned out it might work to some extent for judging functions, but it seems for perception it is the opposite).
"extraverted attitudes" (outside use) are considered "objective", while introverted attitudes are considered "subjective", because they are taking place within the person. Jung had originally defined the attitudes as being focused on "the object" and "the subject". (For perception, the attitude is the "source" it is taken from, and for judgment, it is the source of the "standard" it is based in, and in some descriptions, the "realm" it is used in).
Thinking is also frequently condsidered "objective", based on logic and facts, while Feeling is considered subjective "values".
Sensing (concrete perception) is also occasionally considered more "objective", while iNtuiting (abstract) is considered subjective, because it involves the person drawing from patterns and stuff.
Then, perception in itself can be considered objective, because it is taking information (of an object) in, while judgment is what the subject does with the information.
Objective processing=Perception (P)
Subjective processing=Judgment (J)
Objective data=concreteness (S) or logic (T)
Subjective data=abstractness (N) or value (F)
Objective source=external (E)
Subjective source=internal (I)
Objective processing of Objective data from Objective source (OOO): Se
Objective processing of Objective data from Subjective source (OOS): Si
Objective processing of Subjective data from Objective source (OSO): Ne
Objective processing of Subjective data from Subjective source (OSS): Ni
Subjective processing of Objective data from Objective source (SOO): Te
Subjective processing of Objective data from Subjective source (SOS): Ti
Subjective processing of Subjective data from Objective source (SSO): Fe
Subjective processing of Subjective data from Subjective source (SSS): Fi
This basically reduces the four dichotomies down to one!
