VIVA Transient Measurements Default Settings

Hey, I'm trying to change the default settings in the transient measurements to measure 10% to 90% and also change the base line / top line. 

I've added the following lines to my .cdsenv:

viva.trace threshold string "10_90"

viva.probe baseLine string "0.0"

But only the viva.trace seems to work. The viva.probe is generating the following warning message:

*WARNING* envSetVal: could not find tool[.partition] 'viva.probe'

Cadence version I'm using: ICADVM20.1-64b.

Thanks,
Itay
