EasySocial Dynamic Custom Field development possible?

Hello,

We need to develop a custom field that makes it possible to manage professionnal experiences.


A user should be able to create N job positions in a single field.
A job position is basically made of a title, start and end date, company name and a description.


Is it possible using standard coding guidelines? If so, would you have some hints to provide us with?

Thanks a million.
Sylvain
