Exclude transactions from book to bank

Hello, we are experiencing a lot of difficulty using the book to bank functionality in PeopleSoft 9.1 due primarily to our GL data conversion. As a result we have a lot of entries showing up under GL Adjustments that we would like to exclude from the page. Most of these are entries to prior periods. We also have transactions showing up as Unbooked Payments or Deposits that have either actually been booked that we would like to exclude as well.

Has anybody experienced similar issues and how have you resolved?

In the case of the GL Adjustments, we actually have 1 account for which we can't actually run the Book to Bank process because the process times out due to large number (over 100,000) of conversion entries.
