You cannot add back unless it's flexible, we had all this a couple of days ago, a flexible ISA you can take 100k out and put 120k back in within 1 year for example.
But yes, all gains are tax and allowance agnostic, the only way to get to be an ISA millionaire isn't to add 20k a year for 50 years :)
