Zepto Product Personalizer

This app does exactly what I needed it to do, i.e. create customisable products. Really happy with it. I would suggest 1 update to the app: an easier way to create image sets. One currently needs to add each new item separately. What I would like to do is select a range of images and with one action create a new image set. Similarly for font sets (select a bunch of fonts and create a new font set with all of them)
