Hi SDL team:
This is related with Jerzy Czopik idea https://community.sdl.com/ideas/translation-productivity-ideas/i/trados-studio-ideas/create-a-possibility-of-adding-variables-and-abbreviations-to-language-resources-on-the-fly.
Along with Jerzy's idea, I find very necessary to have a simple way to import a file containing an abbreviation list in translation memories. Having to add the new ones by hand, one by one, is a real hassle. I know I can build an .sdltm.resource file with all of them and use it for new TMs (which I do), but as far as I know, I cannot import this file in existing ones...
