BGP AS-PATH PREPEND

I understand how AS-PATH PREPEND works, but I am not able to make it work if I
need to manipulate traffic paths only from a specific source to a specific
destination.

!
router bgp 65500

 neighbor 10.255.0.26 route-map AS_CHANGE out

!
route-map AS_CHANGE permit 10

 set as-path prepend 65500 65500 65500

router bgp 65501

 neighbor 10.255.0.25 route-map AS_CHANGE out

!
route-map AS_CHANGE permit 10

 set as-path prepend 65501 65501 65501

I need specific traffic from 10.100.60.11 (Source) to specific 10.20.80.11
(Destination) over the 10.255.0.26 connection.

10.100.60.11
_` 10.20.80.11
 

Any thoughts?
