We are migrating from ClearQuest to RTC using *csv export and importing into RTC using custom maps.
There are some fields that don't exist in ClearQuest but we know what they want to be in RTC.

A good example, we want to start all migrated CQ records in the backlog. 

Is there a way I can do this directly in the XML map file? 

Right now I'm opening up the csv file and adding (and populating) a Planned For column before the import.  This doesn't seem like something we need humans for.
