Door leaf without cutouts for lock and handle

[TheImprovisor]

I am planning to equip the interior walls in an upcoming extension with door knobs of the American model.
To avoid reconstruction of the doors, I wonder if there are doors without pre-made openings for the locking mechanism and door handles.

I have searched the Internet but haven't found anything. Maybe you have to contact a manufacturer directly to solve it?

Does anyone have any input on the matter?

There should be no problem arranging it if you speak directly with a door manufacturer. I know that Leksandsdörren is skilled at custom solutions.
