One can define rowID as callback function. For example, you can use

addParams: {
    position: "last",
    rowID: function (options) {
        return 123 + $.jgrid.guid++;
    },
    useDefValues: true
}

where 123 is the start value and $.jgrid.guid is just a counter provided by jqGrid. You can use of cause any other way to generate ids.

The demo https://jsfiddle.net/OlegKi/dnfk8hmr/60/ demonstrates which meaning could have options parameter. It contains just all options of addRow method used in the current call. I used in the demo the code

addParams: {
    position: "last",
    startId: 123, 
    rowID: function (options) {
        return options.startId + $.jgrid.guid++;
    },
    useDefValues: true
}

only to demonstrate, that one can use custom options almost anywhere in jqGrid.
