Add to project but do not deploy?

Monday

I had someone add a slew of objects (Stored procs, views, users, roles, tables) to a production DB outside of my normal deployment with SCA.

What is the best way to go about getting them into my project but making sure they don't try and deploy when I go to prod again? I have already updated my DEV database with these so SCA can now import them into my project. Do I just update the migration script to add a bunch of checks if object exists before the create statements? Or is there another way?

Thanks

I think that's the best solution in this case.
