Rename column without dropping column?

I need to change this:

<attribute label="Email 2.Informativo" name="EMAILRELACIONALALERTAS" type="string"/>
to:

<attribute label="Email 2.Informativo" name="EMAILINFORMATIVO" type="string"/>

But  changing the "name" attribute and ACC wants to drop the whole column. ACC creates this SQL:

-- Log: Updating table 'NmsRecipient'
ALTER TABLE NmsRecipient
ADD COLUMN sEMAILINFORMATIVO VARCHAR(255),
ADD COLUMN sTELEFMOVILINFORMATIVO VARCHAR(255);
ANALYZE NmsRecipient;
ALTER TABLE NmsRecipient
DROP COLUMN semailrelacionalalertas,
DROP COLUMN stelefmovilmarketing;

I only need to change column name...
