**Tell us about your request**
Today ECR Replication configuration only supports `PREFIX_MATCH`. This can cause unnecessary replication when you have repositories that are named with the prefix of other repositories.

It would be nice to have a filterType of `LITERAL_MATCH` where I just specify explicitly each repository I want to replicate.

**Which service(s) is this request for?**
ECR

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
I would like to only replicate one ECR repository instead of all repositories that match the same prefix.

**Are you currently working around this issue?**
Not currently working around as I don't want to rename my ECR repositories.

**Additional context**
**Example**: If I have a repository called `apples` and another repository called `applespice` I can't replicate `apples` without also replicating `applespice`
