Can Xcode Document-based app be set to always open in a new tab

Question

I have an macOS xcode swiftui document-based app. I can see that if I, "view->show tab bar" in the app, I get multiple tabs for free. However, if I do a "file open ...", it creates a new window. Now I eventually found that holding down option when selecting the file will open it in a new tab of an existing window. Does anyone know if it is possible to configure a document-based app to always open in a new tab rather than a new window each time?
