changing the campaign start date

[Clara Bow]

Hi All, I'd like to start a campaign, playing untill i eventually get sunk. Then starting another campaign as another captain from the date i got sunk and basically continuing through the war with the objective of reaching the end of the war with as few uboat losses as possible.

i thought this could be an interesting way to see the whole war without the unrealistic way of realoading everytime i die. Unfortunalty i cant see a way of picking my own start date, only the year. Is there a way to do this?

Thanks
