User Community Feedback

At Lightware we have some project which need to add some external source to Webex Boards.
We already able to add elements to the share tray (for Webex Room Devices), but Webex Boards do not supports the following commands:

UserInterface Presentation ExternalSource Add
UserInterface Presentation ExternalSource List
UserInterface Presentation ExternalSource Remove
UserInterface Presentation ExternalSource RemoveAll
UserInterface Presentation ExternalSource Select
UserInterface Presentation ExternalSource State Set 

So my question is that is it possible to have these xAPI commands, and the feedback registrations on change to the Webex Board?

The benefits:
Customers asked for expanding the HDMI selection list for Webex Boards.
