How to set many attributes with one node?

Third party integrations Node-RED
1

Hello.
I am trying to use Node-Red to create automations to turn on my Window AC with different settings (Fan mode, target temperature, etc), but the call service node only lets me change one thing at a time (set_hvac_mode, set_temperature, set_fan_mode, etc).
Trying to add the other attributes with JSON in the Data part of the node causes an API error because it does not take extra keys.
Is there a way to do this with only one node?

Thanks

Node Red just uses the HA service calls, so if you can not do it in HA, then it is not possible in Node Red either.
Unless you have an access directly from Node Red to your AC.

Why? Just use a call service node for each setting then run them in parallel.
