Hi,
Yes it's possible, for your shipping method description click on the toggle editor and replace the text by:
Choose this method and your order will be delivered to your chosen <div id="chsnOrg">Organization</div> ...
Then in HikaShop > Display > Views, edit the view "checkout / custom_fields" and replace the exiting code by:
<?php
$type = $this->type;
foreach($this->extraFields[$type] as $fieldName => $oneExtraField) {
?>
<tr class="hikashop_checkout_<?php echo $fieldName;?>_line" id="hikashop_<?php echo $type.'_'.$oneExtraField->field_namekey; ?>">
<td class="key">
<?php echo $this->fieldsClass->getFieldName($oneExtraField);?>
</td>
<td>
<?php $onWhat='onchange'; if($oneExtraField->field_type=='radio') $onWhat='onclick';
echo $this->fieldsClass->display($oneExtraField,$this->$type->$fieldName,'data['.$type.']['.$fieldName.']',false,' '.$onWhat.'="document.getElementById(\'chsnOrg\').innerHTML = this.value; hikashopToggleFields(this.value,\''.$fieldName.'\',\''.$type.'\',0);"');
?>
</td>
</tr>
<?php } ?>
If you have many custom fields in the checkout, an "if" condition will be necessary to do the action only if the custom field is the good one.
