How can we help?

I need to validate with a structure like the one provided below. Each object is keyed 1-4 for 4 quarters of the year. Within them there's an object that contains a percentage. I need to validate that ALL 4 quarters percentages add up to 100, otherwise I want to return a validation message. I need to do it per percent field.

  1: Joi.object({
    employees: Joi.object({
      percent: Joi.number()
    }),
  }),
  2: Joi.object({
    employees: Joi.object({
      percent: Joi.number()
    }),
  }),
  3: Joi.object({
    employees: Joi.object({
      percent: Joi.number()
    }),
  }),
  4: Joi.object({
    employees: Joi.object({
      percent: Joi.number()
    }),
  }),

I've tried different combinations of using an expression and Joi.alternatives.conditional() but I don't think I am getting the template syntax right.

Thanks
