Add the ability to merge differences between two stored procedures into a new file that can be ran on the server on a line by line basis.

I.E. 10 lines are different in a stored procedure between a file in a folder and a file on the server. I only want to promote 5 of those differences up to the SQL server, adding the ability to merge those 5 changes into a new file would be super helpful instead of having to copy the file from the server and hand merge them.
