how to use linq dynamic select based on type

I have below class mechanicalData like

public class MechanicalData
{
    public List<LibraryLighting> InternalLoadsLighting { get; set; }
    public List<LibraryEquipment> InternalLoadsEquipment { get; set; }
}

and then i am mapping the fields and forming a list object like as below

private static MechanicalData TransformMechanicalData(MechanicalData sourceMechanicalData, Dictionary<string, MasterSection> masterSectionMappedLibrary)
{
    return new MechanicalData()
    {
        InternalLoadsLighting = sourceMechanicalData.InternalLoadsLighting
                               .Where(a => a != null)
                               .Select(libraryLighting => new LibraryLighting
        {
            Id = libraryLighting.Id,
            IsApproved = true,
            Revision = libraryLighting.Revision,
            MasterSection = masterSectionMappedLibrary["Library Lighting"],
            SourceOfDataId = libraryLighting.SourceOfData.Id,
            LightingDensity = libraryLighting.LightingDensity
            .....
        }).ToList() ?? new(),

        InternalLoadsEquipment = sourceMechanicalData.InternalLoadsEquipment
                                 .Where(a => a != null)
                                 .Select(libraryEquipment => new LibraryEquipment
        {
            MasterSection = masterSectionMappedLibrary["Library Equipment"],
            SourceOfData = libraryEquipment.SourceOfData,
            EquipmentDensity = libraryEquipment.EquipmentDensity,
            Id = libraryEquipment.Id,
            IsApproved = true,
            Revision = libraryEquipment.Revision,
            ......
            ....
        }).ToList() ?? new(),
     }
 }

Is there any way i can apply dynamic type to simplify the above values assign or any suggestion with linq dynamic select query using reflection method that would be very grateful to me, TIA.
