Timesheet Totals

Timesheet Totals

Hi you clever people

We have a form TIMESHEET with the following fields

TIMESHEET_ACCOUNT - (Lookupfield ACCOUNT NAME field from ACCOUNTS Form)
TIMESHEET_START - Date/Time Field
TIMESHEET_FINISH - Date/Time Field
DURATION (h) Formula field - ((timesheet_finish - timesheet_start)  /  (1000  *  60  *  60))
timesheet_transferred_to_accounts - Decision Box

Is it possible to have two read only fields in our ACCOUNTS Form as follows:

Hours Billed - which provides a dynamic total of all the durations where the timesheet_transferred_to_accounts is true
Hours Unbilled - which provides a dynamic total of all the durations where the timesheet_transferred_to_accounts is false
