Hi,
Because AUT and VBS are running in different engines it is not possible. (If you would do this you could have problems with synchronising the autosequences.)
But it is very simple to convert AUT to VBS. If you are in AUTO go to "Autosequence->AUT/VBS Autosequence converter ...".
If converts at least 99% of your AUT and marks the lines which are not clearly like "For L1 := 1 to L2 do" (L2 is for the converter unknown).
I hope this will help you
