Add selecting groups in Price Tags print section

TL;DR
Add group selection in product  label print section ( Now : All products or single product)

Hello, when i want to print price tags i can select either "All Products" or a single product. I would like to be able to select  product group because i have dozens of existing products and can't select my new products manually or just print the whole list. it takes me a long time to select my desired product list one by one.
