@mar5 - this is super cool!
To share it, you could start by making a copy of the Sample Data sheet, add the Tags column to your Transactions sheet in the Sample Data copy, then right click the modified Tags report in YOUR spreadsheet and choose “copy to” and copy it into the Sample Data sheet you created.
Then you can post as a show & tell for Google Sheets with a link to your sample data sheet with modified tags report (be sure to give anyone with the link access to the sample data sheet with the new report).
