Codebuild Rate Limiting

We have been noticing a significant uptick in CodeBuild failures due to throttling, usually when several of our pipelines (that contain CodeBuild projects) get triggered concurrently. The error message is "Error calling startBuild: Rate exceeded (Service: AWSCodeBuild; Status Code: 400; Error Code: ThrottlingException)".

We have several CodeBuild projects and several pipelines, and sometimes several of those do get triggered concurrently. We have currently been retrying these manually. Is there a solution to this that does not involve just setting up automatic retries?
