Creating a new project in 2019 Trados Studio Professional using a mixed-language source file

IDEA: When the source file has more than one language (e.g. FR-CA and EN-CA), the Source Language field should have a "Mixed Language Source File" option that will make Studio ignore any language-related settings defined in the source file. Example: A HTML 5 source file with a language defined for the body. To avoid having to delete this language definition (which you can do in Notepad), Studio should just ignore it when the "Mixed Language Source File" option is used.
