Thank you SO SO SO much, @girish.

Fun fact: the order of the menu buttons changed (for lack of a better word, it is also the word used in the kimai documentation) from CSV / Excel / Print / PDF to CSV / Excel / PDF / Print.

But there is now a fifth template in the PDF dropdown and it has the file name as a name.
Again, thank you so much!!!

• 'app/data/export/'
• '/data/export/'
  I reloaded the cache every time. The additional templates do not appear.

Edit: I suppose it will get an id once it is located and the translation file would translate the ID into whatever "resname" you select. So I should expect to see an ID in the dropdown.

Thank you for your reply in the other thread on invoice templates, but I am trying to add export templates, not invoice templates.

They need to be in a directory called "export": https://www.kimai.org/documentation/export.html

So I tried adding to local.yaml

kimai:
    export:    
                documents:    
                        - '/app/data/export/'

Unfortunately,my templates are not added to the dropdown menu.

When I try to change documents to "templates", I get the following error message when I try to rebuild the cache:

ERROR] Unrecognized option "template" under "kimai.export". Available options are "defaults", "documents".      

When I use "defaults", the default templates disappear from the menu.

kimai:
    export:    
               defaults:    
                        - '/app/data/export/'

So I guess I could try to copy the defaults into the folder and point to defaults.
