How to change logo /dates in numerous word documents without changing each one individually?

[newi1]

I would like to replace a standard company logo in numerous word documents in one process! Also the same with date and issue number.
I am currently saving or copying numerous documents and changing each logo, date and issue number in every file. Very time consuming.


The date is contained within the word document and not in a footer or header.

Any guidance on the best practice would be greatly appreciated.
