How to set value of variable directly in blueprint node, no link to other variable

Greetings!
I create a C++ class and contains several function

UCLASS()
class UBigNumberLibrary : public UBlueprintFunctionLibrary
{
    GENERATED_BODY()

public:
    // 构造方法
    UFUNCTION(BlueprintPure, Category = "BigNumber", meta = (DisplayName = "CreateBigNumber"))
    static FBigNumber MakeBigNumber(const FString& NumberString);

    // 算术运算
    UFUNCTION(BlueprintPure, Category = "BigNumber", meta = (DisplayName = "BigNumberAdd"))
    static FBigNumber Add(const FBigNumber& A, const FBigNumber& B);

    UFUNCTION(BlueprintPure, Category = "BigNumber", meta = (DisplayName = "BigNumberSubtract"))
    static FBigNumber Subtract(const FBigNumber& A, const FBigNumber& B);

    UFUNCTION(BlueprintPure, Category = "BigNumber", meta = (DisplayName = "BigNumberMultiply"))
    static FBigNumber Multiply(const FBigNumber& A, const FBigNumber& B);

    UFUNCTION(BlueprintPure, Category = "BigNumber", meta = (DisplayName = "BigNumberDivide"))
    static FBigNumber Divide(const FBigNumber& A, const FBigNumber& B);
    // 次方运算
    UFUNCTION(BlueprintPure, Category = "BigNumber", meta = (DisplayName = "BigNumberPower"))
    static FBigNumber Power(const FBigNumber& A, const double& PowExponent, const bool& isNeedCheck = false);

    // 字符串转换
    UFUNCTION(BlueprintPure, Category = "BigNumber", meta = (DisplayName = "BigNumberToString"))
    static FString ConvertToString(const FBigNumber& Number);
};

I want to set value of variable in the node itself, and function “CreateBigNumber” seems work it right, I can set a string on CreateBigNumber node. However, in node “BigNumberPower” can not set “PowExponent” and “isNeedCheck” on the node itself, it must link to “get isNeedCheck” node to get value.
