Data Merge within the Slug

[Cisco88]

We often use templates that utilize the slug area of documents to handle file-specific data. Often, we will utilize Data Merge to populate these fields, but we can only do so if our text fields are moved from the slug area into the document. This forces us to move the slug-specific content back into the slug on what can easily be hundreds of documents. Does anyone know a workaround?

Can you extend the text frame so it's just overlapping the page? 
So if it's at the bottom - align the text to the bottom of the frame - then extend the text frame up so it touches the page.

As @Eugene Tyson pointed out - as long as object "touches" edge of the page - it will belong to that page.
