CODECOMPOSER: Assembly code syntax highlighting in CCS-Theia (20.0.2)

Part Number: CODECOMPOSER

Tool/software:

Is it possible to get syntax highlighting in assembly files (.asm and .inc) rather than plain text? It used to work in CCS12.8.1 (albeit not automatically for .inc files)

I've just moved a C2000 project that is heavily on assembly code to the Theia based CCS-20.0.2 and only the .c and .h files have syntax highlighting in the editor.

If it's not in the default configuration is there an extension that might help me?  I tried the C2000 IDEA extension, but it did not help (it didn't say it would but I had hope)
