Hello, I know this is doable. but for the life of me I can't remember how. Currently I have this for my BGP export policy statement, but I need to combine the two /25s into a /24 for advertisement. 

term 1 {
    from {
        protocol direct;
        route-filter xx.xx.xxx.0/25 exact;
        route-filter xx.xx.xxx.128/25 exact;

You can use aggregate and summary-only.

policy-options {
    policy-statement aggregate-export {
        term 1 {
            from {
                route-filter xx.xx.xxx.0/25 exact;
                route-filter xx.xx.xxx.128/25 exact;
            }
            then {
                aggregate {
                    route xx.xx.xxx.0/24 {
                        summary-only;
                    }
                }
                accept;
            }
        }
    }
}
