Home test suite issue when fan speed has "Auto" mode

[Wuttiwong]

i'm developing the smart home device as air condition which has mode "auto","cool","heat"
and also fan speed as "auto", "Level 1","Level2",...,"Level 10"
Additionally , my fan speed "auto" mode has synonym "Auto"

the issue is, when i'm running the test suite.
test suite is trying to change the "thermostatMode" to auto. with the following phase
"Set the [Device Name] to Auto".
however, the google assistant recognize this as set fan speed to "Auto" instead of set ThermostatsMode to "Auto".

is there anyway to change the phase sent by test suite or anyway to solve / mitigation this issue ?
Thank you in advance
