Hi there thanks for posting! Currently there isn't a way to see the title of the whole Google Sheet itself-- but as you mentioned if you look in the data linking panel you can see the title of the page tab that you linked from the Google Sheet (see screenshot my page tab in my spreadsheet was called "NAME OF TAB"). If the page tab name or data doesn't help you find the correct Google Sheet it's in you can always open any potential Sheets directly from your Google Drive change the name of the page tab then come back to Lucidchart and refresh the data set (using the refresh button in the screenshot). If you changed the name of the page tab that's linked the name will update. Hope this helps!
