If you want to take a general reflective metering, the easiest way is to take several separate spot readings from the scene, and then use the average function. You can weight the spot readings however you need to; ie avoiding hot spots in the sky, etc...
I personally find that in situations where I would want a general reflective metering, I'll end up using the incident meter. It's quicker, and likely to be more accurate with 'simple' lighting.
It's a wonderful meter - take time to play with it and get used to the features. There's not a lot it cannot do.
