You'll have to fake it. Here's an approach you might try:
<perhaps>
Make your on-stage field un-editable and place an editable field off-stage.
Use this off-stage field to trap keystrokes and replace existing characters
in your on-stage field.
Use a bitmap/shape/imaging to place your "overwrite" block at the correct
place over the on-stage field and 'blink' it appropriately (timeout object?)
Trap arrow keys to move the position of the blinking block.
</perhaps>
