Inserting data into multiple TS

Is it possible to execute ts.madd command to insert data into non-existing multiple ts keys, thereby to create them if they don’t exist at the same time.
It is possible with ts.add, but I am wondering if the same can be achieved for multiple insert as well ?

Thanks

Not at the moment.
Since each series will likely need its own labels and other parameters, it was not implemented.
