Accounting/Budget Date on Travel Authorization Causing Trouble at Fiscal Year End

I'm wondering if anyone has been able to work around an issue that we have at our fiscal year-end with Travel Authorizations.  The Accounting Date on the header of the Travel Authorization defaults to the submit date.  That is the date that it is also using to determine the Budget Period.  We have a fiscal year-end of June 30 and travelers are entering authorizations for travel next year.  They are failing budget check because they are being budget checked against the current year's budget instead of next year's budget.

Other than telling our agencies to process these on paper until July 1, is there a way to get around this?
