MAX Transit maximum SSIDs supported

Good Afternoon
We are unable to find anywhere the maximum amount of SSIDs supported by the Transit (or HD4).
Now we know that the limit is three SSIDs (after installing the device and requiring 4-5 SSIDs) although more can be entered into the device due to the AP controller functions.
Could you please update your website and data sheets to show that the max SSIDs is three?
Is there any plans to increase this supported SSIDs in the future?
Thank You
