Is there a way to can create an AWS Quicksights dashboard with more than 20 sheets/reports?

Hello,

Each analysis can contain 30 (default) to 50 sheets. Refer [1] You can share analyses and publish dashboards with multiple sheets. However, scheduled email reports only include the top sheet in an analysis.

Use the following list of actions to work with sheets:

To add a new sheet, choose the plus-sign (+) to the right of the sheet tabs.

To rename a sheet, choose the name of the sheet and start typing. Rename is also available from the sheet menu ( ).

To duplicate a sheet, choose the name of the sheet, then choose Duplicate from the sheet menu ( ). You can only duplicate a sheet if Autosave is turned on.

To delete a sheet, choose the name of the sheet, then choose Delete from the sheet menu ( ). You can't delete the sheet if it's the only sheet in the analysis.

To change the order of the sheets, choose the name of the sheet and drag it to a new position.

To copy a visual to a new sheet, choose Duplicate visual to from the on-visual menu. Then choose the target sheet. Filters exist only on the sheet that you create them on. To duplicate filters, recreate them on the target sheet.

You can use the parameter controls on the top sheet to control multiple sheets. To do this, open each sheet that you want to work with the parameter. Then add a filter that uses the same parameter used in the control on the top sheet. Or, if you want a new sheet to operate independently, you can add parameters and parameter controls to it that are separate from those on the top sheet.
