How to change Web Adi Content Text File Delimiter Parameter values?

I have a requirement like to change the Content Text File parameter delimiter values. When we open the WebADI form, content parameters Delimiter values defaulting to Comma(",") and "Ignore Consecutive Delimiters" as checked. But I would like to default the Text File Delimiter as "Others" and Delimiter Character as Pipe ("|"), and "Ignore Consecutive Delimiters" as unchecked. I have used "Web ADI: Download "Text File" Parameters" in Content parameter list.

Any help would be greatly appreciated!!!

Thanks,
