Manual setting of chemical shift tolerance value and default value in general settings

We need a possibility (column/field) to set a chemical shift tolerance value when we do the shift matching of same nucleus type between spectra.
For example, we want to figure out which signals (delta values) in a 1D 13C spectrum match against signals in 2D HSQC spectrum (on y axis in this case for 13C).
To have a tolerance window we need such general settings per nucleus.

But where to place it exactly?
And what is the default value per nucleus?
