Update req.method in vcl_log

Wondering if there’s any way to update req.method in vcl_log routine. Im caching OPTIONS request as link suggests but still need to properly log initial request method.
Ive done some test in fiddle and seems req.method is not getting updated even https://developer.fastly.com/reference/vcl/variables/ says it should be R/W

set req.http.X-OriginMethod = req.method;
set req.method = req.http.X-OriginMethod;

Thanks in advance !

Hi @amassillo could you consider logging req.http.X-OriginMethod instead? I suspect req.method specifically may be read only in vcl_log.
