Stop updating comments in every file

[mbp55]

My model makes one file per class and has upwards of 400 tables. A lot of times, I may need to only update a single column. When saving the model, it checks out every single file and only changes one line in the comments at the top of each file even though there was no change in the actual class. The line in bold below is the only things that is changed.

My team uses source control and because only the comments are changing, visual studio checks out every single file (400 files) just to change that one comment line.
Is there any way to stop all files from being updated when only updating one needing to update one file in the model?

Please open your *.edml model, navigate to Tools > Entity Developer > Model Explorer, select the DbContext template, and press F4 (Properties). Set any value in the Header Timestamp Version Control Tag property. If this option is set, the standard date/time-stamp in the file header will be replaced with the specified tag (e.g. a version control tag for Subversion, Git, etc.).

That worked. Thank you
