Temperature setting on dual extruder, one hotend, Y configuration

My printer does not set the temperature if T1 is active, I have to make sure T0 is selected when I set M104, M140, M109 or M190. So I added T0 to my start and end scrips.
Is there a setting in the configuration file to make it set temperature regardless of what tool is selected?

It sets the temperature for the currently active tool, so just select the tool you need to set temp for and set the temp for it … no ?
