Liquibase Optional Parameters

In the list of Liquibase Optional Parameters, there is one called --defaultSchemaName=.   This is very useful as it allows passing a schema value without hard-coding it in the changeset.   Is there an optional parameter for tablespace name and role name as well?   I could manage without tablespace name, but role name optional parameter is urgently needed.  Since I don’t see it currently in the list of optional parameters,  could you suggest an alternative way to allow passing the role name value in the changeset just as schema name value is passed.  Thank you!
