Use REW in big-venue systems?

(How) can I use REW to measure big venue systems? Systems where the direct sound may have a flight time of ~100ms and ETC of several seconds? Are there any special steps/modifications I need made to make this work?

It seems I have to increase the IR windows, as ETC is not down to -60dB within the default window of 500ms.

Does the FFT length in measurements affect big-venue sweeps in any kind? From subjective point of view, I clearly hear that there is a lot more frequencies simultaneously "in the air" than home theater systems as the frequencies takes far longer time to die down.
