I did. I have sent them a new physical presence calculator and USA Exit /Entry record using Webform.I got the same problem last week in my interview ... I forgot to mention 7 day trip to USA in my calculator form , the officer then asked me to go online and print all USA Exit /Entry record and email them to her ......did that the next day now waiting for her decision ..
----- I suggest you to get it now and mail or email it to them avoiding delays in your application
Thank you for your suggestion
