Is posibly create more than 3 customizer controls?

Hi! everyone, I using Pinegrow and I converting HTML template to Wordpress I have a slider into design with 4 images, for this in Pinegrow I created a customizer section called Slider settings and I configured the 3 customizer control in the interface avaliable with ID’s


and type media with mime type image and setting type them_mod but I want add one more image for example slider-image-4

I can create after adding this in the code manually, but I think that maybe the can made in the same interface, is it possibly?
