WHMCS isn't very flexible about editing the client profile pages, or at least they don't provide documentation for that. Any module aiming to do so will need to edit the template files. We may offer that as an additional module which edits template files
Report type values are editable in the language file within the addon. They are not pre-defined on our side, you can edit the module and send any new types. I'll make sure to include those in the default module, though.
Thanks for the suggestions!
