Current behavior:
Markdown subfilter is only available in YAML import settings.

Available workaround (if any):
Use a complex regex to convert MD code into tags.

Requested behavior:
Add Markdown subfilter option for other file formats, like Multilingual Excel.

Use case:
Some clients use MD formatting inside other file types, like Multilingual Excel. The option to use the Markdown subfilter would enable them to have a cleaner view in the Editor and a more efficient processing of their jobs as a large amount of tags would be avoided.
