RMD and IRS software question

Boy I finally stumbled on how to ask a question. I've bookmarked the link, it's like a maze, awful website.

OK to my question.

Tammy Trogg has let's say 5 IRA's each with a different financial provider. She's up for RMD's this tax year but wants to draw her TOTAL RMD responsibility from just one IRA that is held with "Twister, Trust Me and Bloggs inc" and leave the other 4 IRA's alone.

Is the IRS software that determines RMD withdrawals smart enough to calculate that Tammy has met her overall RMD draw requirements for that tax year or is it going to calculate that she never met her RMD draws as the IRS system sees no evidence of RMD draw-downs from the other 4 IRA's?

Does the system have a global view?? One would hope so, I see that a party can draw all RMD from just one IRA...I'm just wondering what happens on the back end?
