Is there a way to copy the all stages from one match to another?

There is a better way maintaining stage library in the PractiScore apps.

You can build a “library” of your standard stages and avoid cloned matches disconnected from the match registrations.

Go to the match list. Open match for editing you want to reuse stages from and set the “Library” flag in PractiScore 2 apps or in iOS 1.x app or from the match menu on the right select “Library” in PractiScore 1.x app for Android. It will show a “Library” marker on the match.

You can share a “library” match between clubs or within your organization. In this case it would be wise to set the match editing password, as well as the posting results password for the “library” match to prevent entering scores and posting results on the imported “library” match

After importing your match registration using pin# or creating a local match on a tablet you can go to the stages screen and use “Library” option (or “Add Classifier” option in 1.x for Android) to add your stages from the library.
