I need help with the current state of the restriction on second entry to Europe. For the routing:

Africa-Europe-North America-South America-North America-Asia-Oceania-Africa

1. First pass through Europe – no stop over in Europe, not involving South Africa/Mauritius

2. Travel ends in South Africa.

Is it possible to insert a second entry to Europe, with stop-over, anywhere after North America? (The order of Asia-Oceania could be reversed; mileage accumulation is not a goal). Thanks in advance!
