Is there a way to format indicators i.e. number of digits like {load: 8.2} ??

[fooryo]

I would like to have some numerical (float) indicator to be visible with a fixed amount of digits or precision.

Something like {load: 8.2f} for the CPU load indicator showing me float with 8 char wide,2 digits after the point, filled with spaces.

Is it possible? I didn't manage to do that.
