Type in settings in Rig Manager

Can we add the option in Rig Manager to type in specific values for a parameter, rather than just using the mouse?

I know we can fine tune pressing shift at the same time, but still sometimes that does not give nearly enough granularity (e.g. when setting the Monitor Out volume level, which I suppose follows a logarithmic curve, it's really hard to set a low volume when values do 20 dB jump at the slightest movement of the mouse).
