geodir_payment_functions.php override

Hi,
I want to show the “select Package” radio after the description text.

I made a litte change in the file: geodir_payment_functions.php in the plugin geodir_payment_manager

How can I add this change to child theme like discribed here:
https://wpgeodirectory.com/docs/customizing-geodirectory-templates/

Thanks and regards,
Steffen

My modification:
<div id=”geodir_price_package_<?php echo $pkg->pid; ?>” class=”geodir_package”>
 <?php _e(stripslashes_deep($pkg_desc), ‘geodirectory’); ?>

<input name=”package_id” type=”radio” value=”<?php echo $pkg->pid;?>” <?php if($package_id == $pkg->pid) echo ‘checked=”checked”‘;?> onclick=”<?php echo $onclick;?>”> <span style=”text-align: center;”>auswählen</span>

</div>
