I do not think you will find any GRID based client for nay database server doing this. They read from the GRID as SQLyog do (with the the 'smart' keywords and functions as a special featue of SQLyog).
You should start doing a
SELECT allthefieldswhereyouhaveprivilege FROM …..
Now a RESULT tab will open showing only those fields and the update statement will only use these fields in the SQL statement
