How to Resume Tab Order when Spawning a Page

I have a dropdown field that I am using to spawn a page at the end of the document.  When the page is spawned, instead of contining the tab order from the dropdown that spawned the page, it is going to the bottom of the document where the spawned page is.

Is there a way to resume the tab order from the dropdown instead of being forced down to the first field in the spawned page?

I am a coding dummy, so keep it simple if you can 🙂

Thank you!
