You can edit you routing rules during bootstrapping process.

First create bootstrapping class by implementing yiiaseBootstrapInterface

Under Your components directory create a file called DynaRoute.php

<?php

 namespace appcomponents;

 use Yii;
 use yiiaseBootstrapInterface;
 use appmodelsCms;  // assuming Cms is the Model class for table containing aliases
 class DynaRoute implements BootstrapInterface
 {
     public function bootstrap($app)
     {

        $cmsModel = Cms::find()
            ->all(); // customize the query according to your need
        routeArray = [];
        foeach($cmsModel as $row) { // looping through each cms table row
            $routeArray[$row->alias] = 'YOUR_ORIGINAL_URL'; // Adding rules to array on by one
        }
        $app->urlManager->addRules($routeArray);// Append new rules to original rules
}     

}

Now in your configuration file (web.php in config folder) in $config array add above class under bootstrap option

'bootstrap' => [
    .... // other bootstrap options 
    'appcomponentsDynaRoute', // add this line 
],
