How can we improve WHMCS?

Can you provide a way to select a set of plugins and themes from the WordPress repository that will be used on all of our WordPress installations so we and/or our customers don't have to install them manually after WordPress is installed.
I know WordPress Toolkit has preconfigured sets that can be customized and new sets can be created. And, those sets can be selected when installing a new instance of WordPress on a website so, this should be a fairly easy feature to implement.
