Is a role the way to go with this?

We just moved to an Oracle 7 platform, but this site has only one set of books and is a long drive, so here is my question.

The app we have moved over has one Oracle user that owns all the tables/views. Mostly we have users viewing and updating tables via forms and COBOL programs. But this one little piece of the app needs to allow a user to create tables (copies of existing tables) that are owned
by the app master id.

Before when we controlled the horizontal and vertical we used a SQL to do this and had the app master id's password in it. Now that we don't control much of anything we would like a better way.

Can a role be written to allow this one user to create tables and synonyms that are really owned by the app master id?

I got this idea from browsing through the on-line version of Oracle Unleashed at http://www.mcp.com/sams/
