Emergency Help required please

Hi I love the Queen but im having difficulties with Direct to and being able to change my landing destination. Yes I have read the entire manual can do holds and everything else no problems. But during an emergency and having to go direct or returning to an airport for landing. Iam missing something any help would be greatly appreciated. Yes I can do it by hand but there has to be another way. Also does anyone else have this or is this normal my pack 3 always goes off right after startup and I have done what the manual says in abnormal procedures. No joy though. PMDG you have done an outstanding job with the queen I love it just need a little assistance and I know im doing something wrong. Thanks in advance.
