Shared datasource but difference groupings

Is there a way to have a shared datasource, but then define the grouping when the datasource is being used?  For example I have the following datasource that is shared by two different pages

var vendorAlphaDS = kendo.data.DataSource.create({
                                     transport: {
read: {
url: "http://localhost/~termleech/conference/vendors/all",
dataType: "json"
}
     }
});

I have this used by two different pages, but each page is grouped differently.  So rather than have two difference datasources each with the different grouping, I was wondering if I could just add the grouping to the datasource dynamically.
