Geocoder

Is it possible to use the geocoder on a page and have it work within two sections? Here is my geocoder coding:
$addressRecords = array();
if ($myLat && $myLng) {
$maxDist = floatval(@$_REQUEST['maxDistance']);
list($dir_listingsRecords, $dir_listingsMetaData) = getRecords(array(


'tableName' => 'dir_listings',
'addSelectExpr' => geocoder_getSelectExprForDistance($myLat, $myLng, '_distance', $kmOrMiles), // adds '_distance' field to output records
'where' => geocoder_getWhereForDistanceWithin($myLat, $myLng, $maxDist, $kmOrMiles), // optimization: remove results outside of minimum bounding rectangle
'having' => "_distance <= " . $maxDist, // only show results within max distance
'orderBy' => 'ISNULL(_distance), _distance', // sort nearest records first -and- unknown or undefined distances last
));
}

I am pulling from the same table ( 'dir_listings') but have a regular section and a premium section.

list($dir_listingsRecords, $dir_listingsMetaData) = getRecords(array(
and
list($premium_listRecords, $premium_listMetaData) = getRecords(array(
They both use the dir_listings table.

Could I put the two section into an array merge?
$allListings = array_merge($dir_listingsRecords, $premium_listRecords);

I am having an issue with the miles coding because since my geocoder coding is set up to work with my dir_listingsRecords section, I get an undefined index error when working with my premium_listRecords. So I am looking for a way to have it work with both on the same page.

Thanks!
