thank you for your reply. I do not know if what I actually need to do is a test drive I will look into it a little bit more. In the meantime my scenario is the following:
In my organization everyone has an Office 365 account so everyone has also the possibility to use PowerApps.
My objective would actually be that my app could be "cloned" for every project. Each project has its own Sharepoint site with the same list structure. As you know inside our PowerApps it is possible to change the data source so I could change it but the apps needs to be modified. It would be perfect if I could create a father app that someone in my organization can use for a new project and they can specify the link of the sharepoint site without having to modify the app.
Some kind of variable that controls where the app is connected. I am probably asking too much.
