Alternative to TAB layout to show three different pages connected

I have an app where from the home page the user enter in a page built like:

  1. List of all registered documents from which the user can choose one of them and send it to the server with a bottom app bar from which by pressing + the user can create a new document.
  2. New document it's a page FORM like where the user has to compile the data about the document
  3. Body it's the part where the user has to insert all items which belong to that document

For now i show all it in a TAB menu the issue is that there are lot of scrollable elements and a TAB layout it's not appropriate as the user can swipe between views mistakely.

Here is a preview of how it looks like:
