TDP Forum visitor abecker1 has asked for this in a recent post herehttps://forums.toadworld.com/t/group-execute-in-automation/52225.
TDP Automation flows can execute logic by looping through a list of connections, but there's a bit of extra overhead when performing a script execution this way. Group-Execute (to execute the same script on multiple databases) would be simpler to implement and a little faster to execute.
