yes I agree you should always have 2-3 accounts open, especially in UAE.
regarding the compliance, I experienced this morning a request for 7 transactions I did 5 months ago. as I am always prepared for that, they were pleasantly surprise that I answer less than one hour after I received the request.
the more professional you look the better it is. Also always being super polite and respectful, giving compliment, etc.. it always helps to get more flexibility (i.e. if you need a bit more time).
