How can we improve WHMCS?

Hi,

It would be very very useful to display custom configurable options values for each customer when ordering a product.

For example, the customer should be able to choose from his existing ssh keys, security groups, VPCs and other existing resources when purchasing a new server.

I was thinking something like running a custom function in product order page to fill configurable options values (dropdown fields) that get the data calling external API based on customer data.

In our case, this feature would allow us to achieve great flexibility in our service so, I hope that this idea can help others in the same way!
