Could it be possible to customize a default folder for attachments?

- I am using inheritance (org-attach-use-inhetirance).

- But in the headlines in the first level, the :DIR: property needs to be set by hand, always.

- I would like to have a default attachment folder which would be "inherited" by all headlines.

Not sure if that could be a good idea for "org attach group easy customization" menu.

Or if at least I could "hack" it.

Best regards
