FireBase Help : Avoid New ID on new Push

Pushing Data Like This:

myDataRef.push({name : name, text: text});

I don't want every Push to create '-KGD************' entry. I want to add data anonymously, I want all data like this:

web>
    data>
        ran_name>                 //this being first push
            one : 1
            two : 2
        name : esjgnj             //this being second push
        text : gjnse              //this being third push
