Config Custom Rule Evaluations Limit

The AWS Config Put_Evaluations API call has a maximum limit of 100 resource evaluations for a Custom Rule. Resource types such as IAM policies or VPC Security Groups in an AWS Account would easily have more than 100 resources available to evaluate. Attempting to do so, however, results in an HTTP 400 Error: "Member must have length less than or equal to 100"

Splitting the resource array into multiple put_evaluations requests doesn't work; the ResultToken becomes invalid after just one invocation and results in InvalidResultTokenException.

Is this a limit that can be increased? If not, are there any recommended workarounds?
