How can we improve WHMCS?

cPanel has recently released a new version which allows node-linking.

I have setup my new Mail-Only node and am now required to manually setup accounts from new WHMCS clients so that their cPanel account can be linked to the Mail Node.

When creating an account, you can select the linked mail node to take over the mail responsibilities.

I would like to see this as soon as possible as it is a time consuming task having to create all accounts manually.

cPanel's documentation on the Mail Node linkage can be found below, under 'Mail Node':

Thanks
