can you interrupt more than once? Options

[rathmun]

Say I have several IPs, the only mention in the rules as to when you can't interrupt is that you can't take more than the first action from the next combat round during this combat round. Does this mean that (using the MA rules from arsenal) I can use both riposte and finishing strike in response to someone making a melee attack against me? (this would be 2 interrupts in a row, thus pulling my next 2 actions. so as long as I haven't already used my last IP for something I think this works.)

In a similar vein, could I use the finishing move maneuver multiple times in a row? (until I have used the first action from the next combat round, and thus can no longer use interrupts.)
