Yes, have a look for MHSRP on CCO. (Multigroup HSRP)

You can configure multiple groups with different standby IPs but the same
members, like this:(Apologies if I g et this wrong, I'm typing from memory
and not cut'n'pasting)
Router 1
--------
int FastEthernet0/0
ip address 10.1.1.3 255.255.255.0
standby 1 ip 10.1.1.1
standby 1 priority 100 preempt
standby 2 ip 10.1.1.2
standby 2 priority 50 preempt
Router 2
--------
int FastEthernet0/0
ip address 10.1.1.4 255.255.255.0
standby 1 ip 10.1.1.1
standby 1 priority 50 preempt
standby 2 ip 10.1.1.2
standby 2 priority 100 preempt
You then need to somehow ensure that different workstations on the network
use different default gateways.
In your situation, it's worth using standby track to peanalise any router
whose serial interfaces have gone down so all traffic automatically goes to
the working router.

I'm not losing my mind, no I'm not changing my lines,
I'm just learning new things with the passage of time
