Use custom lidar classifications

When converting lidar LAZ files to POD files using ORD, the software picks up the default classifications. This leaves me with al large group of points that are grouped together into the Undefined Classes category.

If I populate the dgn file that is active during conversion with all the additional classifications, those classifications are picked up as well and then stored in the POD file.
The next step would be to store these additional classifications in a dgnlib file to make sure they will be available whenever needed. (hinted to in this post)
Does anybody know what the location of this file needs to be in order to make it available when converting point clouds?

Another option would be to modify the existing file where the classifications are stored, but so far I've been unable to find it.

I'm using OpenRoads Designer 2021 R2

EDIT.

Some more testing resulted in showing me that the classifications are all saved to the POD file, whether ORD shows them or not.
After importing the additional classifications, the POD file will show them separately.

Still looking for a way to have all classifications show up without having to import them into the active dgn.
