How can we improve WHMCS?

I see we have nice options where we can bill metric billing for cpanel and it keeps that information updated. However is there no way to add inode usage to this aswell so when customers upgrade or downgrade it informs them they are over the inode requirements of a plan if they want to downgrade and hence stops support queries.

If there is a hook or a way to enable to already that would be greatly appreciated.

I really think more integration of inodes should be available to be displayed in whmcs as its become more and more of support queries.
