Feature Request: Customizing the Calculator

[KarlR83]

Thanks a lot for your work, I like it.

Do you plan to offer options for customizing the Risk Rating Model (e.g. adding factors like safety, changing the weight of factors)?
I think customizing makes the OWASP Risk Rating Methodology great, so I would love to see it in your calculator.

See step 6 at OWASP Risk Rating Methodology
