Access WEEWX_ROOT in weewx.conf

[michael.k...@gmx.at]

Let's assume this is from my weewx.conf (it is not working this way):

WEEWX_ROOT = /home/pi/weewx-data

[Logging]
    ...
    [[handlers]]
        ... 
        [[[rotate]]]
            filename =  WEEWX_ROOT/log/weewxd.log

Can I access the above defined WEEWX_ROOT in a section below? If yes, how, and is this a weewx or a configobj feature?

A bit of background information is here, https://groups.google.com/g/weewx-development/c/SGSkmxi5L6Y/m/8k9Jk_aSAwAJ
I ended up using a relative path like, filename = log/weewxd.log.

Thanks, but relative to which location? The current dir weewxd was startet from?
