Is there any way to put two different expressions on a single object with DBMS_REDACTION.ALTER_POLIC

As i say above, is there any way to do that without having to create a view of the table on which i want to put a different expression with the DBMS_REDACT.ALTER_POLICY?

I have a table with some sensitive data inside, and i want users (attached to two different roles) to see different column in this table.

I'm using ALTER_POLICY to add a column to be redacted but than i need to change the role that can access that table, but once i alter the expression

the role that can access is now a new one and
