Welcome to the Rush community. You can try Pan and Zoom feature. However, it works only on stills as of now. Check here how to do that: https://helpx.adobe.com/premiere-rush/user-guide.html/premiere-rush/help/effects-panel.ug.html
Please know, this is just the first iteration, and our next Pan and Zoom update will be available in Rush in the coming months. With that update, you’ll be able to set the position and scale of start and endpoints and apply the effect to multiple clips at once.
You can submit the feature request for adding more transitions presets here
