I'd like to loop through all of the select inputs on a page and if the selected value is not a certain option then set that value to selected

I have some selects (notice in select1, option 2 is selected)

```
<select name="select1">
  <option value="1">One</option>
  <option value="2" selected>Two</option>
  <option value="3">Three</option>
  <option value="4">Four</option>
  <option value="5">Five</option>
</select>

<select name="select2">
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
  <option value="4">Four</option>
  <option value="5">Five</option>
</select>

<select name="select3">
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
  <option value="4">Four</option>
  <option value="5">Five</option>
</select>

```

The idea here would be to have a checkbox that when it's checked set select2 and select3 to have option 2 selected as they don't have that option already selected and append a string to the value so I know they've been updated e.g '-updated' 

I'm looping through them like so, but I can't figure out how to set the selected property to option '2' if it isn't already selected and then append '-updated' to the value

```
$('select').each(function() {

    var selected = $(this).find(":selected");

    if (selected.val() != 2) {
        // set option 2 as selected
        // append '-updated' to value

    }

}

```
