Auto-generate

Would it be difficult to prefix the auto-generate SN with the Asset Model Code (and hopefully only use the next highest SN for that model)?  Ie, if I have a Asset model code of "TEA" and clicked on the auto-generate, it would prefix "TEA-" and then look for the highest model code for that prefix.  If I had a "TEA-00100", it would auto-generate "TEA-00101".  However, if I also had a "UTX-0143", and created a new one, it would auto-generate "UTX-0144", not a "UTX-00102".  Not a big deal, just curious.  Thanks!
