A File Output node like this ...
... will generate several images at once (here: A001.png, ..., A250.png and B001.png, ..., B250.png and C001.png, ..., C250.png, all in folder D). For reasons involving different render border settings, I would like to sometimes only render A and B, say, sometimes B and C, sometimes only A, and so on.
Q: Is there a way to "elegantly" switch off generation of individual outputs (I think they are called subpaths)? The only way I have found so far is to disconnect the individual inputs. In order to facilitate disconnecting and reconnecting, I already added reroute nodes nearby. More "elegant" would be a checkbox or the like (perhaps even animate-able)
