Feature request: mapping finds on archaeological profiles (in vertical position)

[vogelso]

Usually, during archaeological excavations, the profiles are also documented (drawing / photo documentation). Often archaeological finds or samples are also taken from these profiles. Since profiles are always vertical, they cannot be located in a common real-world coordinate system. The idea is to create a container or so within FIELD that allows to map a drawing or a photo documentation of such a profile in a separate coordinate system on which then finds or samples taken from that profile can be mapped.
