Doctrine 2 with multiple indexes

I am developing using zend framework and doctrine2.1.

I have generated entities from database.

But the problem is: Doctrine doesn't recognize my indexes. They are not marked in entity annotations at all.

And when I go to validate-schema and dump sql from orm:schema-tool:update --dump-sql it generates sql to drop all my indexes across whole database.

I found that Doctrine has following annotation used for defining indexes:

indexes={@index(name="index_name",
                columns={"database_column1","database_column2"}
        )}

But this allows me to define one index for multiple columns and I don't really need that.
What I want is the ability to define multiple indexes on multiple columns, one index per column.

Is there a way I can achieve this? Is there a way that I can have annotation that defines multiple indexes.
