Convert user tie point to GCP

There is need for more simplified way to convert user tie point to GCP.
This is needed for this workflow without need to export/import points(https://communities.bentley.com/products/3d_imaging_and_point_cloud_software/w/wiki/26852/merging-models)


Workflow:

  1. There is structured aerial dataset with nadir and ground photos of building. GCPs are marked on ground.

  2. After aerotriangulation ground photos are not connected(not in main component) even with marked GCPs.

  3. Some user points are marked on photos from nadir which now reads WGS84 coordinates. Instead of exporting block coordinates it is easier to just clone the block.

  4. After cloning the block with only photo of not in main component there is no option to easy use user tie points as GCPs.

    Another worklfow where it could be useful to adjust nonRTK dataset to RTK where GCPs ar marked with April Tags. As April tags are recognized as user tie points and not GCPs then these can't be reused as GCPs on nonRTK without manually copying coordinates.
