Is there any way to set headers in config?

I am trying something in this way to configure tools.
```
tools: {
...
linkTool: {
   class: LinkTool,
   config: {
        endpoint: 'http://localhost:8008/fetchUrl',
        headers: {
            common: {
                'X-Org': 1,
              },
         },
    },
}
```
