It is certainly possible.
Just create two separate project files Part1 and Part2.
Split the complete project in the middle, save a project file of the complete project with split.
Remove the last half, save Part1 project file.
Re-open the complete project with split,
Remove the first half, save Part2 Project file.
Then produce video or burn disk of each half.
This works on PD 9 or PD 10 or any other version of PD.
