$vbulletin->datastore->fetch(array('customname')) adds 1 extra database call

[pxd]

I've been using the following lines of code to pull custom data from the datastore table:

PHP Code:

$vbulletin->datastore->fetch(array('customname'));
$data = $vbulletin->customname; 


However, I noticed that it adds an extra database call, which means I can't actually take full advantage of the caching system in vBulletin that way.

Question is, would there be a better approach to this to avoid the extra db load to the server? Perhaps another way to hook the "customname" to the default items loaded from the datastore?

Thanks!
