How to bulk add Watcher nodes of Web App Transaction Monitoring

Hi all,  How are you?

I need to add a new watcher node to 100 servers' Web Application Transaction Monitoring.

I mean, I have a list of 100 Web Transaction Monitoring descriptions, and I need to add a new watcher node to each one of them.

It is a painful task to do it through Operation Manager Console, because I have to search for each monitoring description ( in Authoring->Management Pack Templates->Web Application Transaction) , then double click on monitoring, and add the new watcher node on Configure Settings/watcher node. Note that I have to do this 100 times :(

Please, Does someone know if it is possible to bulk add a watcher node to Web Application Transaction Monitoring?How can I do it?

I appreciate any help you can give me,

Rodrigo
