This could be a feature request, but it’s not really needed. If you are using the shortcode on a page to specify a specific group, then you can name that page anything you want (using the group name, for example), or simply type in the group name above the shortcode if you want it shown in the content area and your theme doesn’t show page titles there (or you don’t want to use the group name as the page title).
Originally, each sheet could only belong to one group, so if there was a group specified in the shortcode, it would be redundant to show the group column again since they would all be the same (only one group). Only recently have I updated the plugin to allow sheets to belong to more than one group (feature request from another customer), so perhaps it might make sense if you are using the group column to show all the groups that a particular sheet belongs to. So, that could be a feature request that could possibly be added as an option that can be enabled/disabled on pages where one specific groups is specified in the shortcode.
