URL Slug that accepts random digits at the end of it?

Hey everyone, 

Not sure if this is the right place for this, but I'm hoping to create a custom URL Slug for a page on my website that can accept a series of random digits at the end of it, like this:  https://www.example.com/sn1/#### 

For example, if someone searched https://www.example.com/sn1/1234 or https://www.example.com/sn1/4321 they would be directed to the same page. 

Use URL Mappings to do this. Enter something like the following.

/sn1/[name] -> /abc 301

Let us know how it goes.
