How to automate annotation when Label isn't on DL labels list?

[benjyvc]

I've annotated cracks in concrete using polyline tool in roughly half of 500 images, upgraded to Solo to now automate annotation, only to read in the documentation that "If you have a label that is not on the list of DL labels, you will not be able to match them." Since, cracks in concrete don't match bus, bicycle, or train, etc., is automation of annotations constrained to this (short) list of DL labels? I'm not expecting to automate annotation based on an existing model, i.e. for cars, bikes, or people, etc., am seeking to train a model based on my source data and annotations alone. Is that not supported with CVAT? Thanks.
