Personalize Settings in GL

Hello Every One,

Greeting for the day!!!

Can anyone explain me the personalize settings to add some fields in Withholding tax codes in Gl.

Actually on my AX Screen in withholding tax codes there is only 3 grids viz., Currency,Apply threshold and Reference.

But, i want to add one more grid to that i.e., Tax Type.

And i want to add Components to the Reference grid viz., Settlement period and Receivable Account.

And i want to add components to the Tax type grid viz.,Tax type and Withholding tax component.

For reference please find the screenshots.

Thanks,

Srikanth.
