Question about OracleDynamicParameters usage (is it possible to use NClob in anonumous param object?)

[leqwasd]

Not an actual issue, just a question -

I had a query like this:

public async Task Update(string description, int id) {
    var param = new {
        description,
        id
    };
    await db.ExecuteAsync("UPDATE myTable SET description = :description where id = :id", param);
}

DB type of description is nclob, it worked fine until I hit the point, where description length > 4000.

So I changed it like this:

public async Task Update(string description, int id) {
    var param = new OracleDynamicParameters();
    param.Add("description", description,OracleMappingType.NClob);
    param.Add("id", id);
    await db.ExecuteAsync("UPDATE myTable SET description = :description where id = :id", param);
}

And this works.
Question: If I have a situation, where I need to pass an argument as a NClob - is this the only way to achieve it?
Or is there a way to set the type of an argument using anonymous object like

    var param = new {
        description = new OracleParam(description, OracleMappingType.NClob), // Something like this, I just imagined this line here
        id
    };
    ...

It would reduce the amount of lines that I would need to refactor.
