Can I store sperm?

My partner is going on a fishing trip with the lads for a week on my most fertile week, is there anyway I can store his sperm in the fridge or the freezer and then inseminate myself everyday he's not here? The fishing trip was booked last year but due to covid was cancelled so we had no way of knowing he would be going on my fertile week, he's gutted amd saying he doesn't want to go now, there must be a way round this 😢
