Placing paged documents in an Indesign file

Question

I referencing (placing) one InDesign file with several pages into another InDesign file. When I place it I select Import Options and choose the page of the parent document that I want to show.

My problem / question is that if I insert a new page into the parent anywhere but at the end of the document (beginning or middle) the links that I have created in the Child document get bumped down by one. Ie instead of linking to the page in the parent document itself, InDesign is linking to the page number.

Is there a way to avoid this happening or am I stuck appending new pages to the Parent document at the end?

I am currently using Adobe InDesign CS4

Thanks in advance!
