Hi Darlan and Aankhen,

thank you for your help! In the end a use this setup:

  (org-add-link-type "att" 'org-attach-open-link)
  (defun org-attach-open-link (file)
    (org-open-file (org-attach-expand file)))
  (set-variable 'org-attach-store-link-p t)

I have learned a lot. This is a great project!
Best regards,
Juraj
