I have created an asp.net web API project with angular in the front-end. I have to create a model like this :

but using a formGroup in typeScript will cost a lot of time and energy, same in the backend I have to create a +50 query to store the data.

this.formGroup=this.fb.group({

  siloA1:['',Validators.required],
  siloA2:['',Validators.required],
  siloA3:['',Validators.required],
  siloA4:['',Validators.required],
  siloA5:['',Validators.required],
  siloA6:['',Validators.required],
 .............

in the service .net I have to repeat this code for every input :

shiftTranferStatusAdded = new ShiftTranferStatus
                    {
                        subsystemId = option.silo,
                        unitId = option.unite_id
                    };
                    shiftTranferAdded = _dbContext.shiftTranfers.Add(shiftTranferAdded);

Which are the steps to follow to achieve that?
