Woocommerce Pre Orders – Can i override templates?

I need to override the woocommerce pre-order plugin templates.

I tried the same method that woocommerce uses to override plugins

(copied the templates folder into my theme folder) but nothing happens.

I tried with simple echo “hello world” on the page, but nothing. Is there a way to override these templates?

The plugin structure is the following:

woocommerce-pre-orders
 |_ templates
  |_ email
  |_ myaccount

and i tried to override them like this in my theme (removing the template folder like woocommerce requires):

my-theme
 |woocommerce-pre-orders
  |_ email
  |_ myaccount

and i also tried like this:

my-theme
 |woocommerce-pre-orders
  |_ templates
   |_ email
   |_ myaccount

None of the above worked.

Any help?

thanks a log
