[Feature Request] Is there an option for multiple target language in translation pipeline?

To use the "translation" task pipeline, the tgt_lang kwarg is set to a single language:

from transformers import pipeline

mt_en_fr = pipeline("translation", model="facebook/m2m100_418M", 
              tokenizer="facebook/m2m100_418M", 
              src_lang="en", tgt_lang="fr")

mt_en_de = pipeline("translation", model="facebook/m2m100_418M", 
              tokenizer="facebook/m2m100_418M", 
              src_lang="en", tgt_lang="de")

out_en_fr = mt_en_fr("Hello, how are you?", max_length=50)
out_en_de = mt_en_de("Hello, how are you?", max_length=50)

Is there an option for multiple target language in translation pipeline? E.g.

mt = pipeline("translation", model="facebook/m2m100_418M", 
              tokenizer="facebook/m2m100_418M", 
              src_lang="en", tgt_langs=["fr", "de"])

mt("Hello, how are you?", max_length=50)
