All income for 3 properties reported on 1099-Misc

We own three rentals, but all the income gets reported on one 1099-MISC.

Is it up to me to separate the rents based on rental rate, days occupied, etc? As long as the amounts split up equal the amount listed on the 1099, I should be ok? 

 

It would be nice if my property manager did this for me, right?
