sections window? The sections window would be to put together a set of midi tracks in order.
Do you mean the graphic editor (which has program names) or the tracks window which is titled 'sect 1' at the top?
I've been fiddling with Metro 5 and this is how I managed it......it's probably not 100% right but it will get you started.
I hope this is what you're after.
I started with metro and nothing else.....as I can't locate the metro 5 cd to see if there was an instrument definition on the disk to help you.
An instrument definition is a list that tells metro that grand piano is 0 and violin is program 40 etc.
On the links page was a link to cakewalk and their instrument definitions.

As quicktime instruments are based on standard midi I just downloaded AlesisQS6 as an example.
Unstuffit.
Startup metro and go into program names under the setup menu.
Above the row of 16 check boxes, choose quicktime instruments from the "channels for port" option.
Select the OPEN button near the top and go and open the QS6 file. It tells you the .INS file is opening.
Make sure all the check boxes are ticked and hit OK.
Save preferences to keep these preferences the next time you open.
The QS6 GM can now be selected from the popup and these pretty much correspond with the QT sounds.
Somewhere there is probably a quicktime.ins file out there.
