Using twice same block and defining the settings for both.

Hi,
I was trying to use twice the recent_topics block.
But i wanted to use different settings for each block, in this case is to use the exclude forum ID's.
The thing is if i load both when i go to Portal Configuration i only see on set of settings that i do believe will be applied to both the blocks.
So the question here is if there's some way to do this, using twice the same block type and been bale to define different settings for each one.
I know that i could duplicate the file and edit .cfg file and the .php to use the new .cfg, but i was hopping to do it easily.
Thanks.
