Group Pages Alphabetically

[cuttherug]

I'm not sure if this is already a feature and I don't know how to use it or if this would be considered a feature request, but I'm currently using the tag plugin to create a pagelist and was wondering if the pages can be grouped or separated alphabetically. Here is an image of what I'm trying to accomplish.

Sorry if this is actually a tag plugin issue and not pagelist.

Thank you for any help.
