Quantization and continuty in video timeline segmentation

Hi, I’m using label-studio 1.13.1 and I’ve been doing a video timeline labeling segmentation with a configuration similar to the default one. Is there a way to have only selected regions quantized to video frames? And also a way to have not superimposed regions in a easy way? I’d like to avoid to put the number by hand of two continues regions to have continuity.

Thanks in advance
