Embed an instance of a frame into another page

Hello!

Is there a way to create an instance or a viewport of a frame from the same file in Figma? Essentially, I’m looking to have frame A1 that is the exact copy of frame A and update with any changes. I don’t want to create a component of my frame A because I would have to create a lot of them to make a whole flow.

How would I use it?
My team likes to have a representation of all the pages of our web app in a flow in one single page on Figma, for example Basket → Detail → Phone → Payment → Confirmation

But because our designs are complex and have a lot of variations, all designs are separate in our Figma file, eg one page for all variations of Basket.
