Yes there is. Using Shift ↓ or Shift ↑ , select the lines on which you want to include multiple cursors. Then press Ctrl Shift L to split the selection into lines. Finally, pressing ← will place the cursors at the beginning of the lines, and → will put them at the end.
Edit
There is another, faster way (thanks to minitech) - Ctrl Alt ↑ / ↓ will create several cursors without first making the selection, and you can place the cursors anywhere on the line you want. However, on Windows, these keyboard shortcuts can be displayed to change the screen orientation. To change this, press Ctrl Alt F12 to open the Intel control panel, press Options and either reassign the screen orientation hot keys, or press Off on the left side to disable them all.
