replace 2 key fobs with one programmable

I have a 1994 Toyota Camry with an aftermarket Clifford XL500 alarm system and an Autopage RS-60 remote starter. The key fob for the alarm system needs to be replaced because the existing one is damaged. Because I have two fobs on my keychain at the moment, I thought it would be nice to remove the need for two key fobs and replace it with one programmable fob. The two different remotes would be programmed to two different buttons on the new fob. I've looked online, but I can't seem to find what I'm looking for. Does something like this exist? Can it even be done? Thanks.

No because you have 2 different makes with incompatible programming and frequencies...except have you actually tried to program one to the other, or if the R/S has an enabling trigger, use an aux on the Clifford to effect this.

Just looked at your R/S, sorry it doesn't have one.
