How to dynamically create correctly in UrlManager for static pages?

Question

Yii

I'm making a static page module and I want their urls to be two-level, /about/contact and not /static/about.
In the menu of the main page, I display links like this
['/pages/default/view', 'alias' => 'about'],
in the url manager

'<alias:(about|stock|contact)>' => 'pages/default/view',

Question: how can I dynamically create a rule in urlManager when creating/changing a new page in the admin
