Unclosed polygon labeling

I am trying in my project to build a dataset which requires connected points that is to label a zigzag lines (unfinished polygons). Couldn't find this feature in label studio.

**Describe the solution you'd like**
Add another type of label called ConnectedPoints exactly a polygon but allow "unfinished polygon". For now, If you use polygon labels you can't make a new polygon until you finish the previous one. I want to have an unfinished polygon to make connected points (unclosed loops).
