Not easily at least.
You can take the positions and generate a layout.xml file using a layout xml from your capx as an example. So you'd save the generated file somewhere, close your project in c2, and assuming you had saved your project as a folder you can replace one of your project's layout xml with the one you generated. Unless there's a mistake in the xml that was generated.
Anyways it's probably a tedious thing to do initially, and the step requiring you to manually replace files is a slow workflow.
A more reasonable thing to do would be to save the generated positions to some text, and then put that into your game and recreate the objects from that.
