Can I pump into the same bottle for 2 hours?

As a super under producer I get so tired of having to pump and wash pump parts after each pump. I only make 10-20ml each pump session. So I was wondering if it would be safe to pump into the same bottle same pump parts for 2 pumps In a 2-3 hour span? If that makes any sense? Bc I know milk can stay out up to 4 hours in the right room temp before having to use/refrigerate it.
