Bill a report to different projects

It's a requirement that we bill all or part of an expense report to one or more accounts.

Made-up Example:
Total expenses for my trip to San Francisco, including meals, hotel, etc. was $1,000. My report total is $1,000. This total must be billed 50/50 to "Member Relations" and "Project Planning".

Is there some way we can accomplish this aside from adding it into report comments?
