Set Member in Table Row

So i am using Tables since i think they make excellent Database structures, but no, i cant set members in them making them sort of only readable.
Anyone know why this wont work?

So the set exists and is being executed but the data is not changing?

Its there because Data Tables are structures i guess, i did a workaround for now but it would be cool to have this feature, the work around has nothing to do with this question, only added an array on my character and then added all the learnt crafting on him.

Oh, so despite “set members” nodes, it’s not possible to set Data Table values from blueprints?

Thats correct, nothing get changed.
