BGP aggregate-address with advertise-map

Can this be achieved with an advertise-map ?

On R6 I receive 4 routes via EIGRP and redistribute them into BGP then send
it via EBGP to R4.
On R4 I need to get a summary-route and the specific-routes for 200.0.0.0/24and
200.0.1.0/24.
I cannot change the aggregate-mask.

R6
router bgp 200
 aggregate-address 200.0.0.0 255.255.252.0 advertise-map ADVERTISE
 redistribute eigrp 10
 neighbor 158.5.46.4 remote-as 100 --> R4

route-map ADVERTISE permit 10
 match ip address prefix-list EIGRP
!
route-map ADVERTISE deny 20
!
ip prefix-list EIGRP seq 5 permit 200.0.0.0/24
ip prefix-list EIGRP seq 10 permit 200.0.1.0/24
