I found an old message (WPM SEUM Invoke tests from API? - Forum - Web Performance Monitor (WPM) - THWACK) about 'WPM SEUM Invoke tests from API' feature not existing and need to be proposed.
How do I find out whether this feature exist Or how to propose the feature?
To find out if it exists you can use SWQL studio to see if there is a related verb for WPM (called SEUM in the database or SWIS tables). The verbs have pink icons. However I looked under Orion.SEUM.Transactions table and do not see an option to invoke test. Only create, remanage, manage.
To create a new feature request, or search for existing (if its still out there) you can go here.
