On the Task List tab of Calendar Properties, I see that you can select an Index to use for sorting, but I only have a few options. Can I create a custom index to use for sorting the task list?
You can create a custom index to be used in the Task List via File Maintenance.
To create a custom index for the Task List
In the Quick Launch, search for and select “File Maintenance.”

Enter the new Index ID for your index.
Enter a Description for your index.
Select the desired Sort Order.
Click Done.

You can now select this index for the Task List in Calendar Properties.
