Allow notifications only for workflows?

[xgo]

I just started leveraging file actions more seriously (a lot of value in using 'move to' on selected files using a hotkey). I am irked by the constant notifications showing me moved files:

 

Now, I do have some notifications that I need (or leverage for debug) in some custom workflows, so the solution isn't as easy as 'just disable notifications entirely' as suggested/solved here. Is there any way to implement a customization of notification per category? For instance, I'd like to remove all file action notifications, but retain OS-level notifs for workflows installed.

 

Thanks,

Xavier
