You can do that in Magos Model Editor.
For attachment points, go to the Node Manager, right click and choose Create new Attachment, then name it and find the right coordiniates.
If your model shall have a portrait, you should make an anim called Portrait.
You also can open your model in Magos, go to Camera Manager, right click and choose "Create a new camera from current view". I don't know it it's neccessary, but I always call the camera "Portrait"
Then just save the model under a new name.
It has to be saved as "YourModel_Portrait.mdx"
Then just import "YourModel.mdx" and "YourModel_Portrait" and it will work all fine.
I hope I could help you
