The server sets up the path in ManagedRepositoryI.createTemplatePath.
The project or screen into which the import is occurring that was
requested by ImportLibrary via
http://downloads.openmicroscopy.org/latest/omero5.4/api/slice2html/omero/grid/ImportSettings.html
is passed through the server's ManagedImportRequestI into the metadata
store's TargetProcessor for linking. That's available at import time but
it's only after the metadata step of ManagedImportRequestI that other
container names encoded in the uploaded files themselves are known. Of
course, the template path setup is done before the files are even
transferred to the server: it broadly relies on what it is told via the
import settings to figure out what that path should be so the
configuration options at
https://docs.openmicroscopy.org/latest/omero5.4/sysadmins/fs-upload-configuration.html#template-path
fit within what is then known.

Sorry it's not easier! Generally the repository path structure is of
most interest for:

* offering read-only network mounts of repository subdirectories based
on the group into which data was imported
* ensuring that new imports arrive onto new disks that still have plenty
of space, e.g., as at
https://docs.openmicroscopy.org/latest/omero5.4/sysadmins/repository-move.html#extending-the-managed-repository
