Hi @Nino_Munafo
Welcome to the Forum!
As it stands, we don’t currently have a “preview mode” for project planning. There is an existing thread in the #productfeedback category suggesting this feature. In case you haven’t yet, I’m pinging it below, so you can upvote it and comment.
Adding to what @Joel_Charles has recommended, I would also suggest you to have a look at the following thread, specially this post from Allen: Template assigned tasks show up in My Tasks automatically? . You might find it helpful!
Please, let me know if there is anything else I can help you with!
