In Crystal Reports, can you create a formula field dynamically

I want to create and add a formula field at runtime. Is it posible?

Thank you in advance!

Do you want to insert a new formula field in an existing rpt from an application that you are developing?

AFAIK, We only can modify an existing formula field at running time from an application

But, if you post the Crystal Reports version and your programming language & version, perhaps some other member could help you
