Unfortunately the only way to change a date on a card is by taking it and giving it back.
It's a superficial thing considering it's highly unlikely you'd ever give it away but in trades like that and even in re-rolls (where users immediately get a card they are rerolling back via a trade) we take it/give it back to update the date.
That way users can't re-roll the same card again the next day as the date still shows they can.
In a similar situation, being aware that we'd remove a card and give it back, uwu asked us to put the original trade date within the description of the card. It's likely you told me you completed VIVIZ in my thread (or made a completion thread) so I can find the date and put that on your card description if you like?

And yes, putting that the card should go "straight to ---" in the trade will be fine.
