ARIS Test Designer (SAP SolMan) - subordinated elements handling

Dear colleagues,
while selecting the test model first time in the test scenario we are asked if existing content should be deleted (message attached). If we select the option Yes, all existing test variants will be removed from the scenario.
We need feature how to manage preferences centrally for specific Test design project (allowing or disabling of this feature and message)
Thank you in advance.
Regards, Daniel.
