Can you pump and store colostrum

My boobs start hurting super bad and the only way I can make them feel a bit at ease is by realising the colostrum that accumulates, it’s not tones each time sometimes there is more than other, but I’m just wiping away what ever is there and I’m thinking could I be storing and saving this for baby, and how would I go about actually doing that/what are the guidelines for it. I have a planned c-section for the 15th of October so I’d know exactly when then to take it from the freezer idk I’m having to relieve my boobs daily so it seems like a waste and if I don’t do it they hurt like crazy, I’m 37 weeks today.
