Insert URLs in Roon metadata

I’d like to be able to insert urls into one of the “edit album” metadata fields so that within Roon I could navigate to a page about the recording. Sadly, many digital recordings don’t include the cd booklet. Any ideas?

The only way to do this right now I can think of is creating a pdf with an URL inside and place this pdf file in the album folder. Would be a rather awkward way to get what you want.
