Hi Scott,
Currently this request not in the roadmap, I'd recommend you to
submit an idea about it.
We have recently added the
Campaign Target URL to improve in-zone campaigns performance.
This allows the RTP script to load relevant campaigns only on the target pages where they suppose to be display, once visitors match the segment.
What you can do in your case is to set the segment to match visitors on specific pages only (
See "Specific Pages" section) and use wildcards. Then, instead of setting a Target URL, enable the 'Any Page' option.
Let me know if you have any further questions,
Yanir.
