If you have multiple events that have similar seating charts, you can copy and paste an existing chart to save time creating your next event.
How to duplicate a seating chart
Once you've created your first seating chart, use the 'Select' tool to select all of your seating chart design.
Click the 'Copy' icon at the top of the editor.
Close the chart editor.
Click 'Create new seating chart'.
Click the paste button.
You can now make any edits you need, using your original seating chart as a basis.
