Bundle services - full price and itemized

I have a situation where we charge for the internet service but also have some other fees that need to be included in every internet package. Thing is that I need them itemized as well with their individual prices. Is there a way to do this?. Right now, I’m adding an internet service package and 2 recurring items for every subscriber. While not a huge deal, if the management wants to do a % off promo, I have to enter that information 3 times.

Hope this makes sense. If not, I can post an example
