Shift-Select - Ctrl-Deselect

This is the standard for so much other software, is it possible to implement in Illustrator?

It's extremely useful to be able to select a group of objects by dragging, and then deselect items by dragging - but in Illustrator, you will inevitably include unintended objects, and end up endlessly toggling the selection / deselection status. In CAD, it's very simple - one button to select, another to deselect; drag one way to select all objects inside, dra the other to select all objects partially inside. Even other Adobe software like photoshop has the shift-ctrl difference. I'm confused as to why Illustrator doesn't.
