Hey I saw your post during the power hour. If you're going to be providing the value to check for (i.e. "Washington"), you could use a filter action and join the values of the stops to see if they contain that value. The filter action would still return your full (but filtered) array of records.

For your filter action input, enter your array of data.
For the filter query,
join(item()?['Stops'],',') contains 'Washington'
