During project creation, we select the source and target languages first and then add the project files. It would be handy to be able to tick or untick target languages for some of the files during project creation. For example, if a client sends 5 English files and wants all 5 files to be translated into French, but only 3 of them into Italian and only 1 into Spanish, it would be handy if we could specify this during project creation (instead of having to add and prepare the files first and then delete them for certain target languages).
