Question about column/block select methods

First of all, I know that you can perform temporary column selection by holding alt and dragging your mouse, and that you can activate the mode permanently with alt+shift+ins.

What I would like to be able to do is hold down alt+shift, create the selection via the arrow keys rather than the mouse, and return to normal selection mode once I clear the selection.  Notepad++ supports this and exhibits precisely the behavior I would expect (for reference, in case an example is desired).  Is there any way to enable this functionality in IntelliJ?  If not, is there any public avenue of submitting an enhancement request for future versions?

Thanks in advance for any and all responses.
