Questions Revenue Recognition challenges

we have a client that ships containers of product internationally.   the sales invoice date must match the bill of lading/vessel sail date, but for long trips, revenue cannot be recognized until the product reaches the destination port, sometimes as long as 6 - 8 weeks.   the invoice would ideally be released in the invoice date's period, but needs to credit deferred revenue until the revenue recognition date.

does anyone have any suggestions for how to best handle this in Acumatica?  

thanks in advance for any suggestions, especially if they keep me from calling on my buddy Rube Goldberg.
