Is it OK to use Tom's and Jim's room to say the room belongs to both of them?

In the grammar books that I can lay my hands on, it's only logical to say Tom and Jim's room, if the room belongs to both of Tom and JIm.

It's often logical in English, where two names have a logical pairing for some other (presumed) reason, that you would PROBABLY say "Jonathan and Rebecca's baby" -- for example. That sounds 'natural.' The 'logic' is fairly clear in that one. But there's nothing immediately wrong *to me* with the 'Tom's and Jim's room' phrasing, for example. It just might be less common, that's all. And you'll probably end up (if more explanation is needed) by saying: "They share a room." as the very next thing....

I think if you say Tom's ans Jim's it refers to 2 rooms.

on the other hand if you say Tom and Jim's, it is more like as follows
(tom and jim) 's


It becomes a collective group rather than 2 separate cases.

remember ho (2+6)/2 is different from 2 + 6/2 in math's. Similarly think of (tom and jim)'s
