SG data entry math

given that you already support mathmatical operators in most entry fields....can you implement a custom operator? 

Perhaps for entering gravities with their temperature?  EG: 1.046@75F automatically is adjusted to 1.048 (assuming a hydro calib temp of 60F).

A new option could be added in equipment for hydrometer calibration temperature....

Simiarly for volumes? 

Thanks,
  That is a great idea - I will certainly take a look at it!
