Adding new offers

We are new to Ontraport, and there are a few things that Ontraport just won't do. 

I was trying to see if there was a way to default "subscription settings" to any product or product bundles we have created within Ontraport, for any time we are putting in order manually. Since this wasn't an option, on live chat I was suggested to create an offer, sort of like a template, so our team can just select the offer, and the rest of it will auto populate. But I can only create these "templates/offers" either inside a customer account or within a landing page. 

But what if I have a product bundle and no landing page for it? I want to see if there is a way to create these offer templates ahead of time, so whenever one of our team members goes within a customer account, they can just select from a drop-down menu and the order will be ready to be charged - sort of serving like a one-click offer.

Can this please be implemented?
