e-Bike Battery Level doesn't include Range Extender

Hello, I have a Specialized Turbo Vado SL with a Range Extender connected. The problem is my Garmin 1050 is not reporting the extra capacity provided by the Range Extender.

For example.

My internal battery has 75%

The Range Extender is full. (Specialize call this 50%)

On the Vado SL, this is reported as being 125% charged. (75% internal battery + 50% extra for the range extender)

But on the Garmin, it is just reporting the internal battery level. Showing 75%.

Are there any plans to properly support these range extenders so the full battery capacity is shown on the Garmin 1050?

Many thanks.
