Hi @Mr_wais - The community has come up with a few different ways to do this in the past. You can check out the below link from SNGuru on how to control the execution of request items in an order guide.

Note that the article also links to another article on how to link the request to the order guide that created it. In Quebec, you don't need to do this step, as the order_guide field on the Request is automatically populated for you OOTB.
