web to lead: upload file field and hidden fields

Hi,

We currently maintain a website where we use form assembly to collect data from a contact form. Our client recently started using Zoho as a CRM and would like to have that data dumped into the web-to-lead area. I know about all of the export/import csv options. I'm ideally looking for something more automated.

A couple questions:

1. I see that form assembly has an export to SalesForce option. Has anyone heard anything about form assembly offering the same functionality for Zoho?

2. As far as I can tell you can not add an "upload file" field to the public zoho web to lead form, is this correct? Has anyone found any work arounds?

3. It also seems as though you can't add hidden fields to the public zoho web to lead form, is this correct? I would like to use hiddens fields to grab data. I know how to add a hidden field to the html although since Zoho is not Open Source it doesn't seem possible to implement the code that re-out-puts that data into the zoho interface. Does this sound right?

4. Finally, I've looked at Zoho Creator and it seems to allow more form flexibility/functionality. Although I didn't see any way for Zoho Creator to automatically send data to the web-to-lead in Zoho CRM. Is there any automated way of doing this or is transferring data via CSVs the only way?

Any feedback would be great!

thanks!
