Default Movement Member Selection - Cash Flow

Summary:

Client has a requirement for a systemized cash flow in FCC. They will continue to load ending balances where we load to ClosingBalance_Input and rely on the default movement assigned to each account member to populate movement for cash flow. They have a sizable number of monthly journals and plan to transition from YTD journals (their current process in HFM) to periodic journals in FCC. We will also have data input forms to make movement adjustments.

However, when posting consolidation journals, they do not want to select the individual movement member for each account and would rather rely on the default movement member selection. Has anyone had a good experience for defining a process that is best for populating movements for journals?
