Specify a different icon for each network drive

I have several network drives mapped to my Dopus drive bars. I wanted to know if I can assign a different icon to each of those drives to make it easier for me to identify them, without having to go to the tree or having to place the mouse on the icon for the tip to come up.

I expect this technique will work, though I haven't tested it with network drives:

[HDD Letter Icons)

Thanks a lot for the technique. I have tested iot and it works perfectly with network drives!!!!!!!
