In Step 2 of the wizard, determine which rows you want displayed in your presentation.
Now comes the fun part — determining how you want your image of the project to be created. This is the next step in the wizard.
If you have already selected rows prior to starting the wizard, then you can specify that only these rows be displayed. If you want to select different rows, you'll have to exit the wizard, select the rows you want, and then restart the wizard.
If you want to show a particular time period, you can specify the new time in this page of the wizard as well.
Your presentation is almost ready to be exported into another program.
