The Smartsheet Source is written to pull data from a single Smartsheet spreadsheet. Unlike Google Sheets, Smartsheets only allows one sheet per Smartsheet - so a given connector instance can sync only one sheet at a time. To replicate multiple spreadsheets, you can create multiple instances of the Smartsheet Source, reusing the API token for all your sheets that you need to sync.
