in all the remote site you will need to use the as-path list "ip as-path access-list 1 permit ^$" under bgp and send it to the remote neighbor. So your local router will send all the local networks. If you do aggregate-address x.x.x.x x.x.x.x summary then only the summary of the component metrics of the same network class will be send in addition to another networks.
for example: if you do aggregate-add 10.2.0.0 255.255.0.0 sum and network 10.255.1.10 mask 255.255.255.255 then both 10.2.0.0/16 and 10.255.1.10/32 will be send to the neighbors

Hi olivereng20,

yes you have right in the second part from your post, but we use "p as-path access-list 1 permit ^$" for another perpose here, we use the command to match the request " none from remote site must be a transet area or AS, that means all the SP routers must see only the local prefixes from the remote sites. so they DO NOT send them anything else.

Thanks.
