Create customized Deal/Potential/Lead from Email Parser

Create customized Deal/Potential/Lead from Email Parser

Hi,

trying to create a potential (which is a copy of the original potential with lot's of modified fields) by using the Zoho Email Parser. But the customized modul is not shown at all. 

Secondly I tried to use the lead module in Email parser, but the modified lead modul is not shown I can use only the values from the original one. 

Does anybody have an idea how to fix this? 

Regards Peter
