post to multiple forums at once?

[webaus]

I am wondering if there is an addon or function that allows the admin to make one post either in the forums or admin that can be copied to multiple selected forums?

For example if i want to make a post announceing somethign in say 10 forums, currently i have to post in one and manually copy to each forum one at a time

I do realise there is the announcement function but id prefer not to use that

and also i need for it to work in such a way that when i make the copy to the other forums, anyone subscribed to that forum gets an alert

currently the standard copy function doesnt do this
