Sheet Format Search / Auto Update

Hi there,

I have 100 drawings in a project which I have inherited that need to have title block information changed from an old company to a new company.
There are a few different sheet formats that I have seen so far and wondered if there is a way to search the project files for .SLDDRW but be able to see/filter by .SLDDRT

Once the new .SLDDRT files are created with the updated information, is there a way for these to be automatically updated across the project or do I need to have to go and manually update each drawings sheet format properties?

Any help would be much appreciated.
