Is it possible to use system env variable in userdata.properties file for logs.dir

iwx1

I have defined a System Variable as SAHI_LOG=C:\SAHI_LOGS\logs
In the Sahi userdata.properties we define logs.dir=logs
Instead of "logs" above is it possible to use %SAHI_LOG% or ${SAHI_LOG} ??

OR Is it possible to define logs.dir while launching sahi dashboard which will take the actual value of the env variable?

Thanks
