We will be working with several clients on the same database.  Each client will be importing their leads through a web to lead platform on each of their individual business web sites.  We would like to utilize the campaign functionality to identify each lead to the corresponding client.  Can we use the web to lead workflow that starts in the campaign module new lead feature?  

For each client we would use the html code from the individual campaign web to lead coding?

Example:

Client A fills out a web to lead page and sends it.  We receive the lead information and the corresponding client / campaign is attached to the lead already.  

Thoughts?
