High Level Assembly language is not recognized

Hello dear moderators. I have a repository with *.hla files, which is source code from the High Level Assembly programming language, also known as simply HLA. I would like them to show up as just Assembly, although it would also be good if High Level Assembly would be created as a separate designation.. But unfortunately Github does not mark the programming language in my repository. Please dear moderators fix this issue.
