Create multiple ROI in same image in App Designer and store the data in a struct

I have an image in an axis i App Designer in which i can plot as many ROI's as i'd like using drawcircle. My problem is that i would like to give each ROI a uniqe label and also save the data from my ROI in a struct. Is this possible?

Just append it to your structure:

roiStruct(end+1).roi = yourROI;

yourROI could be any form, for example an ROI object, or an N by 2 array of (x,y) coordinates, or a binary image, etc.
