Nope. I have asked for it since the switch to XenForo with nothing happening, same on every Xenforo I am on.
Really annoying and should be a simple check box on the control panel but apparently that is not something that XenForo will allow.
The software only appears to allow a single, global setting and I recall wwilson changed it a few times after the switch. Don't know if Xenforo has an add-on module that allows more configurations but he's said a) modules typically cost $ and b) he wants to avoid too much customizing because it's add'l time and work following s/w updates/upgrades (both of which I won't disagree with).
