Question - Multiple Storage Accounts "Logstash Azure Blog Input"

This might be a quick answer as I couldn't find an answers on the readme or old tickets:

We have multiple storage accounts that we need to pull NSG flow logs from (right now 10 and growing) from.

do I need to create a new input file for each or would I expand this section?

input
{
azureblob
{
storage_account_name => "mystorageaccount"
storage_access_key => "VGhpcyBpcyBhIGZha2Uga2V5Lg=="
container => "mycontainer"
}
}

Thanks
