Unfortunately, I'm not sure your question really makes sense? Why would you need two ATOs?

Side note: I have two ATOs but it's for redundancy. They both do exactly the same thing. I don't think that's what you meant?

You could hook your RO/DI to a resevoir with a float valve and a pressure activated auto shutoff. You could then put the ATO pump in the resevoir.

A couple of things to keep in mind.

While it is rare, if the float valve fails you will have a flood.
This setup will cause premature failure of your RO membrane and you will go through a lot of DI resin. For your RO/DI to work properly, it needs to run for extended periods of time rather than on/off/on/off/etc

What I meant by 2 ato's is one for the resevoir and one for the tank itself. I am not interested in having to remember to fill a resevoir all the time.

What I would really like is to just install an ATO straight to the tank. I suppose that abcha0s suggestion to add a float valve to a resevoir would be my next option. I have been researching a DIY solution to this problem but I am not to crazy about trusting my limited skills to do so.
