Basically for each property I want 3 options to choose from:  
1) Update value if blank  
2) Append to value  
3) Overwrite value

Sample use case(s):  
Append Option: Notes Field  
I have a comments field on my contact form where someone sends us a query. If that contact later submits another query I don’t want to lose the previous info from my records. I want to see the new information appended to that field. (Can’t keep creating new properties and using smart properties).

Overwrite Option  
Standard as happens curently with most fields, if a contact enters a new phone number it overrides the previous data to keep it updated with the latest information.

Update if Blank option - Lead Source  
When a lead comes in, I assign the Lead Source to it, but I only want that updated if there is no previous Lead Source assigned to it. I don’t want subsequent forms to overwrite the value. Smart Field(s) works only partially because if I use the API to submit forms, smart fields do not stop it from being overwritten.

Thanks
