Case Sensitivity in eventtype searches

I want to make a group/eventtype with events from a certain sourcetype where LOGINID="I*" and 'I' is capital only. There are some solutions for case sensitivity up on answers already, but they all involve piping to a function or regex. And when you go to make an eventtype Splunk does not accept search queries with pipes. What can I do to make this search case-sensitive?

You can create a field extraction that uses the case sensitivity of regexes to create a new field only if the first character is uppercase or lowercase. For example:

SOURCE_KEY = LOGIN_ID
REGEX = (?<LOGIN_ID_UPPER>[A-Z].*)

Note that this relies on LOGIN_ID being a regex extracted field, since automatically extracted fields are processed after regex fields.
