Mapping between opaque review IDs and old numeric IDs

I have an existing system that fetches reviews for an app from the following URL:

https://itunes.apple.com/en/rss/customerreviews/?id=[numeric app ID]

The response from this URL gives review IDs in numeric format, for example 11990822406.

I'd like to use the new API described here to fetch any review response, but the new API only accepts an opaque review ID, for example 00000037-1653-fg99-8224-821b00000000.

Is there any way to map from the numeric review ID to the opaque ID?
