Check if multiple data cursors can be selected in LiveScript files

Please see attached a Live Scipt file and a mat file.

I wanted to know if it is possible to place multiple data cursors on a plot within a Live Script.

I wanted to be able to highlight all the peaks.

I have tried holding down the "Shift" or Ctrl" key, but it only selects the peaks one at a time. What am I doing wrong?

Is there a way of doing this programmatically?

Any assistance would be much appreciated.
