Disable auto planned completion date on issues.
Does anyone know how we can disable the planned completion date from defaulting to the entry date/time? I know we can put in a default duration of 1 day etc, but we would actually prefer it to either come in blank or to default to the date added in a custom field. (on specific issues only). Looking back at several existing issues and they have "not available" in the planned completion date field. That would be perfect for this need but I cannot find any setting on it that makes it behave that way. Plus if I enter an issue now on that same project it auto creates a planned completion date... Any ideas?
