Is it possible to remove indoor temperature from clientraw.txt?

use this version
http://www.weather-display.com/downloadfiles/weatherdisplaytest.zip

and set in the wdisplay.ini file, before starting up this versipn (and after exiting WD)
[indoortempclientraw]
option=no

and then the indoor temperature and indoor humidity will be set to zero values in the clientraw.txt file
