Dynamic Excel Spreadsheets - can they be merged?

I understand how we can use a single Dynamic spreadsheet to update records, but can we merge more than one Dynamic Spreadsheet into one workbook to allow records to be dynamically updated?

I am thinking of a list of cases, account addresses with a separate financial table (from a third party system) perform some VBA and for each case processed to update the Case Status.

The Cases table would be two way, the account addresses one way (refreshed to live)

TIA
