Hi MAT on FHIR team,

We are trying to copy and paste the content of the following FHIR libraries into MAT. All of these libraries retrieve code systems specified in another library, e.g., FHIRCommon."SNOMEDCT", but MAT does not recognize this type of logic and prompts an error message "Could not find code system named FHIRCommon."SNOMEDCT". Please advise, thank you!
