Hi all,
Looking for the best way to complete switching on an API from Loan Origination Software into my SF Org. Challenge I'm facing is, I'm currently using the standard object Lead to house all of the Lead data, and I have two objects "Closed Contact" (standard object Contacts with only contact information) and "Closed Transaction" (custom object that houses all of the loan data from LOS). the API will help communicate all of the "In Process" loans that we have but I don't want to build out a 4th Object to house all of this data. I'm thinking I can do this one of two ways: 

1: Simply rename "Closed Contacts" back to "Contacts" and "Closed Transactions" to "Transactions" and reconfigure the fields based on what I  need for the LOS and have the LOS directly map the API field names to use the Leads object for the Leads status files, and everything else to import under the Contact and Transaction objects based on their statuses......OR....
2. Build out another custom object, "In Process".
***I would need to incorporate processes to also migrate data from multiple fields on the Leads object to multiple fields on both the Closed Contact and Closed Transaction page layouts if the status were to change and remove them from the Lead status and place them into "In Process", which I'm also not sure of how to do***

Is this even possible? If you're still reading this, thank you for your help in advance!!!!
