There is no option on the developer console for this afaik. If there is it is not prominent or easily discovered.

However, I saw a small burst of bad reviews on an app I used to work on a few months back - all of those reviews including the developer replies are now 'missing'.

Its possible they merely flagged the reviews and Google got rid of them because they were rude. Possibly the OPs removed them because the developer got in contact to ease their pain somehow...
