Lambda@Edge - Maximum number of distributions with Lambda function exceeded

I have a Lambda@Edge triggered by a Cloudfront Origin Request that simply removes a part of the resource path before requesting the origin.

My issue here is that I have a lot of distributions (maybe 50) for which I'd like to trigger this Lambda function, but apparently, the only thing I managed to trigger is the:
TooManyDistributionsWithLambdaAssociationsException

com.amazonaws.services.cloudfront.model.TooManyDistributionsWithLambdaAssociationsException: Completing this action would cause the maximum number of distributions with Lambda function associations per owner to be exceeded (maximum allowed is 25).

Moreover, I am surprised I don't find it in this documentation:
http://docs.aws.amazon.com/lambda/latest/dg/limits.html

Can I get round these limits somehow?
I'd be grateful if someone could explain it to me!
