Hello,
I ask for this in the How-to forum and have no answer, so I believe this isn't possible today.

Well , here is my request for new feature .
Implement some automatic Permanent Links creation, as "clean urls" for pages and albums ?
For links like :
* https://fotos.imartins.com.br/index.php?/contact/
* https://fotos.imartins.com.br/about.php
be accessible as
* https://fotos.imartins.com.br/contact
* https://fotos.imartins.com.br/about

And for albums : 
* https://fotos.imartins.com.br/index.php … 2017-09-23
be accessible as
* https://fotos.imartins.com.br/cimtb-2017-09-23

I used to get this at Drupal content manager automatically... it is very nice way to link..
To be used as inspiration or a code as example, this is the Drupal plugin with that functionality: https://www.drupal.org/project/pathauto
