Making a Static list - smart

Hello!

As part of an integration with AdRoll, I want to import lists from Marketo to AdRoll

To my understanding, Only static lists can be imported.

I need my lists to be dynamic so I was thinking about a solution

Creating a smart list and a static list

> smart campaign adding every person on the smart list to the static list

> smart campaign removing every person whose > Data value changes (as needed) & a member of the static list (a batch and a trigger)

Is that something that might work?
