When adding a new dossier, create list from template file

Hello,

this would be a nice to have feature but is not important. However, it would enhance the user experience and user friendliness. 

When adding a dossier, I would love to see an option where I can create a new list based on a list template (STP) file. I know there is the regular way, just open the site where I develop the solution and upload the STP to the list template gallery and create a list and from the add dossier pick existing list. 

If we could select that STP file from the add dossier (list create) dialog it would speed up things.

Cheers and thank you for considering.
