.gitattributes for custom/options

This might be more of a feature request, than a support question. I tried to find a solution in the docs, however if there is one I did not find it.

I would like to achieve for the user to have an option/dropdown box selecting a .gitattributes template to use with the [] Initialize Repository option. Similiar to the way .gitignore is provided.

It seems to me this would be a valid use case for a git workflow?
