How to edit label text in Wix Code?

I am, too…haha. I guess the answer is that they are grouped together? Basically, we are using a Product Page template that has various settings (layout, displayed options, etc.). But this appears in the editor as one grouped item with ID productPage1. Among the optional items that are displayable using this template is Quantity; we want to kinda repurpose this with a different displayed text label. It seems that the editor does not allow picking out the subelements of this single templated object. And there don’t appear to be any options to relabel the available fields.
