Concatenate fields in Identity Item

I would like to be able to concatenate desired fields in my identity item, so that I would be able to send my contact info faster, without copy-pasting every single field.

How I imagen it: one would be able to define a new kind of field in your identity item, where one could define the format of the output, while using existing fields. If original fields are updated, the concatenated field would also update automatically.

For example, my concatenated address would be defined as:
“[First name] [Last name] /n
[Address 1] /n
[Zip / Postal Code] [City / Town] /n

Not sure if I tagged the request correctly. Appologies.
