Spell Check ignore repeats
 

The sheets I'm spell checking have many, many, many, many, many, many, many
identical pieces of html code in it that I am not interested in
spellchecking. So, now every second it tells me "Repeated word", and my only
options are "ignore ONCE" -- not even "ignore all".. Basically, it's copy I'm
proofing, don't care about what the code says, just need the words in the
copy. Would love to delete all the offending code, but cannot. :(

If anyone has any suggestions, I'd be thrilled to hear them! Thanks!
