Get all translations of a specific key

[abd-el-rahman-abd-el-zaher]

We can use this now to get the current language translation
this.translate.instant(key);

so can we use something like it to get all translation for this key
for an example if we have ( en , fr , ar ) languages we get an object as a result like this --> { en : "value" , fr : "value" , ar : "value" }
