Make "dot" and "hat" closer to the letters?

The left two symbols are \dot{z} and \hat{z}, respectively, created using this tool. However, I prefer them to look like the ones on the right, which are created by typing \dot{z} and \hat{z} directly in Word Equation.

Can I get the "dot", "hat", or "ddot" closer to the letter using this tool? Thank you.

The proper code for a dotted letter (with the dot close to the letter) should be

<math xmlns="http://www.w3.org/1998/Math/MathML" display="block">
  <mrow class="MJX-TeXAtom-ORD">
    <mover accent="true">
      <mi>z</mi>
      <mo>&#x0307;<!-- ˙ --></mo>
    </mover>
  </mrow>
</math>

However, this tool lacks the 'accent="true"' part. Is it possible to add this part back for the tool?
