validCheckSum in formatted sql

Is it possible to place a validCheckSum comment in a liquibase formatted sql.  I tried the following and it did not work.  Is there a different way to register a secondary validCheckSum value?

--liquibase formatted sql logicalFilePath:test-file

--changeSet auth1:id1

--comment: ...

select '1'
