Can You Tell When You Are Switching/blending With A Part?

I m feeling rather badly posting this question because I ve not been very active on the board for a while (so am feeling selfish about asking for feedback). I seem to be going through some particularly confusing weirdness regarding dissociation. For any of you with DID or OSDD...can you tell when you are in a "part"? If you can, how do you do it? (That is, when you are flooded up/blended with/switched with a part versus being WITH a part from a larger self perspective?) I keep being... Can You Tell When You Are Switching/blending With A Part?
