I don't believe this is currently possible (but correct me if I'm wrong) so I will raise it as an idea.
When a procedure is added as an action on a block in a dataview layout it defaults to displaying the name of the procedure when the user hovers/clicks on it (as below) with the word 'Run' at the beginning.
Often the name of the procedure is not as meaningful to the end user as it is to the developer, often due to naming conventions etc.
This idea is to enable the displayed text to be customised to display something that is of more meaning to the end user.
Currently the only workaround I know of is to create an additional procedure with the text you wish to display as the name, and then have this procedure call the actual procedure you need to run, just adding complexity through an extra procedure layer and one more thing to administer.
