Can an account owner take an RMD from one retirement account instead of a separate RMD from each account?

The IRA owner is required to calculate the RMD separately for each IRA they have, but the amount can be withdrawn from the total amount from one or more of the IRA accounts.

However, RMDs that are required from other retirement plans, such as 401(k) profit-sharing plans, cash balance plans and other defined benefit plans, must be withdrawn separately from each of those plan accounts.
