Question
Is it possible to create a custom unit for Pressure?
On our BOM we need to indicate filling pressure for tyres, so it can be used to generate work instructions and service manuals etc. For a given wheel and tyre combination the filling pressure might change depending on which product it is used on, so we want to treat it like oil, water or grease and add 1 usage of 'COMPRESSED AIR' to the EBOM and indicate quantity of 'COMPRESSED AIR' in psi or bar.
