Adding Ecommerce to an existing project using a template

Hi, I think I already know the answer, but some earlier posts implied that there may be a way of doing this in the future.
We have an existing Webflow site that we are happy with, but now we would like to add e-commerce to it (Now that Ecommerce is available), is there any way to ADD a template or elements of the template to an existing site.
I had envisaged that I would have been able to buy a “bolt on/add on” solution.
Having to either add all our existing site information to an Ecommerce template, or do the Ecommerce/shopping cart etc. from scratch in our existing site would be a huge overhead.

Many thanks.
