Add new groups and categories

[Avedena]

Hello,
I am currently working on an human segmentation dataset and want to contribute a custom model.
The main question is, how I can add to the existing model new groups and categories?
Its enough to name the training data properly?
For example:

22#Human#1#Standing_Front#abc.jpg
22#Human#2#Standing_Back#abc.jpg
22#Human#3#Sitting_Back#abc.jpg

Have you also a list of the v2 groups and categories to match my training data yours?
Thanks

I did train on a custom human segmentation dataset and the results are good but still some errors. Not sure about categories. Did you acheive any good results and might share the model/dataset?
