Import ODT into Wordgrinder using terminal command

[ubuntupunk]

I get that Wordgrinder is able to convert its own content into odt on the command line and that it can import ODT from within its ncurses menu. What I want to do is be able to open odt in wordgrinder using mimetypes and cli file manager like joshuto. In other words, having a flag like wordgrinder -i (import) odt (file type)

I don't want to convert odt into wordgrinder format in order to pipe the output to wordgrinder, but rather flag wordgrinder to import the odt from outside the programme.

Would this be relatively easy to implement?
