How can we improve WHMCS?

Hi everyone! Hope you're all doing great.

There are no API functions related to Product Configurable Options. Specifically, our requirement is to add Sub Options to a Configurable Option programmatically.
For example, if we have a "Disk Size" config option, be able to create via the API a sub option like "100 GB".

It's a simple requirement that we think could be useful for some cases.

Thanks in advance,

Eric
