Another approach is to make your shapes the one with Add Shapes (Ctrl+1).
Text Inside then will fill both.

If you want to reposition then switch to the Shape Tool (F4) and select all nodes to move or alter and use the arrow keys or mouse.
The shapes need to be one above the other for this to be useful.

Just tried Break Shapes and this still works. You need to use the Edit inside > Select shape option or use Ctrl pick in the Page & Layer gallery.
Any change to any shape throws all the text into one of them but after making changes, reAdd (Shapes) and all reflow properly.
