Start Query in Web Template

In OSS Note 1056259, it suggests: If you use several queries in a planning application, you should use the option of only starting queries using commands when you actually require them. I would like to follow this suggestion, but no where do I see an option to not start the query. I have a web template with a tab structure. Each tab has an embedded web template with two queries in each. I want to try and make sure that the queries are not executed until that tab is selected. Any suggestions?
