Can no longer choose to overwrite collections when importing from a file

When importing a collection with the same name as an existing collection postman used to ask whether I want to overwrite the existing one or import as a copy.

Now postman always imports a copy and does not give me the option to overwrite.

I have had a look in the settings and can’t see an option to get the old behavior back.

Was this a deliberate change? Is there a way to make postman overwrite collections when importing?
