Input text (Objects) does not allow more than 250 characters

Hi everyone, 

I'm trying to create an input text in Objects (capabilities.json) and it has more than 250 characters. I saw that the component has the maxLength = 250. 

And I saw in documentation there are just: 

export interface ValueTypeDescriptor {
    text?: boolean;
    numeric?: boolean;
    integer?: boolean;
    bool?: boolean;
}

However, I need to use parameters with text in my visualization.

Is it possible to create a textArea in Objects? if so, how?
