Set attribute value for all Services/Routes

Is there an option to set default attribute value once for all Services/Routes?

For example, override the following default values for all Services:
“retries”: 5,
“connect_timeout”: 60000,
“write_timeout”: 60000,
“read_timeout”: 60000

And override the following default values for all Routes:
“strip_path”: true,
“preserve_host”: false

Thanks

There is not. I’ve heard such requests before. A github issue would help to track this feature request.
