How can I find a partial matched value in redis and update if it already exists?

Question

Currently, I am using sadd to insert address:number. Is there a way I can check if the address exists on a partial value match and then update/replace it with the new value?

    //Update payout
    var payoutUpdate = [];
    payoutUpdate.push(['sadd', coin + ':userPayout', [addr.split('.')[0], userPayout].join(':')]);

    redisClient.multi(payoutUpdate).exec(function(err, results){
        if (err){
            logger.error(logSystem, logComponent, 'Issue with custom payout!' + JSON.stringify(error));
            return;
        }
    });
