It looks like what you need is to create a feature request, as it sounds like the driver is working as intended.
As a general rule, the built-in drivers may not cover every capability that a device offers, but rather the basic capabilities. For (more) advanced features, usually the community fills in the blanks for omitted capabilities, by developing a custom driver. If a missing feature is highly popular, then our engineers may consider enhancing the driver when the time permits.
