Diffrent groups can be configured for diffrent IP pools.
For ex-
asa(config)#ip local pool SSLClientPool 192.168.100.1-192.168.100.50 mask 255.255.255.0
asa(config)#group-policy SSLCLient internal
asa(config)#group-policy SSLCLient attributes
asa(config-group-policy)#address-pools value SSLClientPool
Same step can be repeated for diffrent groups and diffrent IP pool.
