Interceptor for Authorization headers using Kendo UI datasource

I am using webapi and restrict web api's to authenticate by token, so to populate datasource I use request headers in DataSource.

var abcDatasource = new kendo.data.DataSource({
    transport: {
        read: {
            url: '/api/exampledata',
            dataType: 'json',
            headers: { 'Authorization': 'Bearer ' + accesstoken }
        },
    },
    pageSize: 5, 

});

the below line of code need to repeat at all datasource

headers: { 'Authorization': 'Bearer ' + accesstoken }

Is it possible to make central function which overwrite the kendo datasoruce headers that provides the token to the request headers? because i have more than 600 datasources, I just want to have token setup in one place.
