Should I change my Slipping CVT's fluid?

Hi all, I'm sure this is a question you've gotten a million times, I am curious what you all think I should do.

I recently was given my parents old 2015 Nissan Versa with 246,000 miles which I'm really thankfully for with how expensive cars are these days. Now unfortunately the car was never really maintained, and has never had the CVT fluid changed.
Overall it drives ok. It has always slipped a little bit since I had it, (about 10,000 miles), but never felt unmanageable.
After about 2 hours of driving it now will slip at anything more than 15% throttle, once in a "gear" it will drive ok, and it cruises well enough on the freeway. It can still get out of it's own way, but the classic failing cvt rubber banding under heavier acceleration. (it will jump from 2,000 rpm to 3,500 when trying to accelerate when the car get's warm)
How bad the slipping is seems to be dependent on how long I've been driving, so I'd imagine it has something to do with heat and how broken down the old fluid is.
It is worth noting there are currently 0 fault codes, engine or transmission despite the obvious problem.
Now, i'm well aware this transmission is totally done for, but would a fluid change help or hurt extending the life of the transmission at all? Are their any additives that might help?
I was hoping to make it last a few more months until I can afford to do something about it and just in general make it last as long as possible.

Advice would be greatly appreciated,

thank you so much for your time.
Sorry but the life of the transmision is over..you had a good run.. it's time to replace it, changing fluid won't help
 
I don't mind the car, the cost seems to be about $3,200 for a new transmission, but nowhere near me seems to want to rebuild it. I was debating doing it myself, but most places want to charge around $280 for the fluid
Shops can't rebuild CVT transmissions, they have to go back to Nissan. Because there are no serviceable parts and the special machine to install and tighten the belt is extreamely expensive
