When Example Data has been added to a Data Sampling Panel in Lt, can I no longer sample into that Panel?

Adding Example Data to a Live Sampling Panel in Lt can be done by pressing Shift + Left Click on the Start Button, and choosing 'Use Example Data'. This will prompt the Student to enter a password to access the Example Data (defined under Course | Settings as an Admin):
servlet.ImageServer?id=015w0000002v1Ca&oid=00D20000000HncM
Doing this will switch the panel to 'Example Data' Mode, showing the Student all configured Example Data. However in this mode Sampling and Deleting Data are disabled, with the relevant buttons being greyed out. To switch back to 'Live Sampling' Mode, simply Shift + Left Click the greyed-out Start button, and choose 'Use Student's Data':
servlet.ImageServer?id=015w0000002v1Cu&oid=00D20000000HncM
This will then allow data to be deleted, and re-allow Sampling (added Example Data will still remain in the panel).
