Editor - Inject Blank/Static Options into Dynamic Option List

Hey there,

I'm having a issue with the Select2 plugin where the plugin requires a blank value as the first option so that the field doesn't default to the first option in the list (a legitimate value). I need to inject my own options.

fields: [
        {
            "label": "User Group Visibility:",
            "name": "TaskType.UserGroupVisiblity",
            "type": "select",
            "multiple": true,
            "separator": ',',
            "options": [
                { label: "No Group Association",    value: "Any" },
                { label: "Tech",    value: "Tech" },
                { label: "Truckload",    value: "Truckload" },
                { label: "Pricing",    value: "Pricing" }
            ]
        }

Like the example above basically, but I need the options that come over with this as well to combine into the predefined options. (see below for my server side code)

Field::inst( 'TaskType.UserIDAssociatedTo' )
            ->options( 'Users', 'id', array('EmailAddress', 'FirstName', 'LastName'), null, function ( $row ) {
                return $row['FirstName'].' '.$row['LastName'].' ('.$row['EmailAddress'].')';
            } )

Secondary but partially related issue, I have my table set to refresh the data at specified intervals using the code below

setInterval( function () {
            table.ajax.reload( null, false ); // user paging is not reset on reload
        }, interval );

But it seems that when i do this it is resetting the value of the select2 plugin to the value it was initialized with instead of what is in the record I have open to edit.

I'm happy to provide access to the page if someone can take a look.
