Dynamically changing include path with RPL

Hi.

I'm trying to dynamically change change the include path of a content file dependant on the customer and I'm running in to a few issues.

Scenario

I have a content file for each product we sell (say, 200). Based on customer data from an abandoned search, I want to bring the content file relating to their abandoned product like so - <#include "cms://contentlibrary/abandoned/${abandoned_search.product}"> etc.

The process works absolutely perfectly when previewing the email, but frustratingly, proof and live launches are prevented in the campaign because it's validating the unrendered email, so it's seeing "cms://contentlibrary/abandoned/${abandoned_search.product}" as an invalid path and preventing it.
