Using old DSC keypads with new panel and DLS?

I upgraded my PC5010 to a PC1832. The LCD5500Z keypads seem to be working just fine with the system, but DLS-5 won't talk to them and there doesn't appear to be a module definition to add below ver 3.0. Mine are 2.1.
 
So in order to add all the new zone names for the zones I'm adding, I'll either have to program one of the keypads manually or I'll have to use my old PC5010 on a bench with one of the keypads hooked up to it to program the labels.
 
Am I missing something? Is there an earlier version of DLS that still works with the older 5500 keypads but still works with 4.6 of the PC1832?

I may be wrong, but I believe my panel is a 4.6 revision and I used the older DLS 2002 at first before finding a download for DLS-5. You may want to try it and see if it'll support the older keypads and newer revision board.
