Example:
aggregate-address 1.1.3.0 255.255.255.0 route-map AGG
neighbor x.x.x.x unsuppress-map ONLY_THIS_ONE
route-map AGG permit 10
match ip add prefix SUMM
!
ip prefix-list SUMM seq 5 permit 1.1.3.0/24
ip prefix-list ONLY_THIS_ONE seq 5 permit y.y.y.y
So y.y.y.y is the only route out of the routes on which your aggregate was based, that will be advertised along with the aggregated address.
