ImageJ max group size

I have been using imageJ/FIJI for awhile now and ran into an issue. Does anyone know how to increase the maximum number of groups? I reached the 256 group limit and, after searching, I may have to change some of the source code. Does anyone know how to increase the maximum group size?

There is a limit of 256 groups and no easy way to increase this limit. Use the Edit>Options>ROI Defaults dialog to assign names to group numbers. As a shortcut, double click on the rectangle tool icon to open this dialog. Use the Edit>Selections>Properties dialog (shortcut: ctrl-y) to assign ROIs to groups. You might consider using ROI names or ROI properties to work around the 256 group limit.

Ok, Thank you and I will try this
