[.86] Bug?/Suggestion - Existing Enchantments not Scaling with new shards

Maybe this is by design but existing enchantments like burning blade and evade don't scale with newly build shard shrines of the appropriate element. i acutally have to dispel the enchantment and recast it to get the benefits of the new shard. while not game breaking it is a nuisance. a lot of times i forget as i have to remember when my shard shrine finished building and what enchatments i have already casted, not to mention waste more mana casting the spell again.
