Wish: accessing post effects via render command option

I haven’t really used the post effects and the other options available in the sidebar of the RenderWindow so far. Since I usually render batches via macro I don’t have any way to make use of these options. I wish there was a way of making the effects accessible through the Render command. Some effects could save additional post processing in other programs like photoshop.

Btw, one effect that I’d like to see added is placing a watermark.
