Calculated Fields in ACS

Hi there,

When creating new fields in ACS (profile resource extension or new custom resource) is it possible to create calculated fields like you can in Campaign Classic?

I mean using an expression attribute expr="xxxx" to make use of the functions or create concantenations of other fields, like you can use in the expression editor.

I've seen the default age field is a calculated field. e.g. expr="YearsOld([@birthDate])"

But is there a way to do this for custom fields?

Thanks

David
