Is there any Polygonal labeling tool in MATLAB 2017a?

I'm using image labeler in Matlab 2017a. But I'm unable to find any option to make the ROI a polygon(it's rectangular). Using a rectagular ROI is not sufficeint for my requirements. After online Matlab Help pages, I got results with polygonal labeling option. But that is available in Matlab 2020 it seems. Upgrading wont be easier due connection speed limit at my home. So is there any way I can do this without upgrading to newer version of Matlab?
