Linking Configuration flows from 2 separate models as Start Node and End Node

Hi,
We have a requirement in Oracle CPQ involving two separate models: 1. X 2. Y

Our requirement is to create a single flow experience where depending on the condition from commerce we first show the configuration flow from X as start node and then configuration flow from Y as the end node and vice versa The goal is to allow the user to configure both models within a single configurator session without exiting the configuration or returning to Commerce between the two models

Questions: 1. Is it possible in Oracle CPQ to link 2 independent models so that their configuration flows run sequentially within a single configurator session ? 2. Can the start node of one model transition to the configuration flow of another model ?
