Copy Variables between Blueprints

Same problem here! I have 20 variable in one bluprint, and have 10 different bluprints that I need to copy this variables to. I can’t copy bluprint because they are different and the difference is huge. Basically this bluprints are completely different that should have some similar functionality but still different. So I need exactly to be able to copy variables. Can’t even believe this isn’t something you can easily do…
