Chartroom is very customizable and you are likely to produce many chart templates that you will want to use again, so saving them in a dedicated spreadsheet is good practice. Google Sheets is also a sharing environment so you are encouraged to share your custom charts with the Chartroom community.
Chartroom also publishes Chartroom Mastersheets. You are free to copy these sheets and adapt them for your specific purposes.
There is no need to save standard pool play and lives play as Chartroom creates these on the fly.
