Chris, the trick is to either remove and re-apply the Link > Pop-up layer action or set it up as your last commit; no need to move the blobs around.

To control a host of different reveals and timings.
Place a shape in Menu(lock) and Name it 'blob' or as you fancy. Make it Repeat on all pages.
For all reveal animations, include the trigger object name: blob.

It is still a pain to set up correctly.
