[Plugin: Fast Secure Contact Form] Extending shortcode

Is it possible to set default values using the shortcode? If not, that’s a request as it would be a really nice feature.

Let’s say I want visitors to be able to sign up for different events. I have a large number of events and there are new ones added continously. Instead of editing a selectbox in my form each time, I would like to be able to do something like this;

[si-contact-form form='1' event='Pub crawl, Nov 22nd']

“event” being a hidden field in my form which tells me which event the visitor signs up for.
