Another Dometic toilet question - water level adjustment

[SteveM4037]

We have two of the Dometic toilets in our 2019 Ventana LE, I believe they are the 8700 series with the wall mounted fill/flush pad. I know how to switch from dry bowl to wet bowl modes, and we have had no real problems in 2+ years. (Except for guests holding down the button and changing modes! Not the best design.)
My question: is there a way to adjust the water level when in wet bowl mode? The half bath toilet always has less water than I would like after the flush/refill cycle is complete. Have to use the "add water" button every time. The water level in the main bath toilet is noticeably higher when the flush/refill is complete so don't need to use the "add water" button.
Just a bit of a nuisance.
Thanks in advance!

On our LA when contacted Domectic on the water level which is control by the black tube attached to the toilet discharge. By moving the tube up and down controls the level in the toilet. Our water level was low in the rear bath so it wasn't to hard to change by opening the emergency rear door to get access. Need to move up or down the section with hose clamp to change water level.
