That's possible, but you have to customise your script.
You do not do anything, it will be automatically created if table has file fields.
Just create a field by choosing form type = checkbox in form and you have to set the values in 'Form Names' and 'Form Values' also. The script will generate the add_form, search_form as what you want.
You can add a link like: <%if Email%>Email:<a href="<%Email%>"><%Email%></a><%endif%> in your search results page. Email is the name of a field.
