Generating a period report with day book entries through the API

Hi,

I need to create a customized reporting mechanism for accounts similar to Reports -> Period total. Account_GetEntriesByDate from SOAP API can be used to get entries in a specific date range for an account, but it skips day book entries.

Is there a simpler way to get all the book entries for an account (preferable within a date range) than do it manually (and heavily ineffectively) with CashBook_GetAll, CashBook_GetEntries, CashBookEntry_GetData for every entry and later filter and sum them in memory on my side to generate mentioned report?
