solr4 - Solr Update Substring of Field

Question

Is it possible to update part of a field in Solr 4.4? For instance, I have a field containing URL values, and I want to change the domain but preserve the rest of the URL. I know how to update the entire field to a new value, and that works fine, but this would be like a substring replace.

From: {"id":1234,"title":"Some Title","url":"https://someolddomain/asdf/1234"}

To: {"id":1234,"title":"Some Title","url":"https://somenewdomain/asdf/1234"}
