I'd like to automate the creation of the product schedule when an opportunity product is saved.  I think that I should be able to do this relatively easily with an APEX trigger this using the process builder...but I'm not a developer.  So it's also entirely possible that it's not easy.

Essentially I'd be taking a custom field "Net_Total_Amount__c" and dividing it evenly daily in between "Start_Date__c" and "End_Date__c".

 How difficult is something like this to set up?  Is the basic premise sound?
