Hello @laucaly, I think that would be very difficult to do since various areas of measurement increase differently over sizes. That's why they are grouped. I think one should rather look at changing the measurement chart used for a pattern and have various standard measurement charts for the different groups of measurements.
One needs to create your own Standard measurement charts that will suit your needs. Just make sure that you use the same measurement descriptions in each. Unfortunately, the smallest base size is 22 and the smallest base height is 50, which excludes new born baby sizes and doll clothes patterns. I guess one could make various individual measurement charts that will handle these.
