I’m not sure on that, I’d need to find someone who hasn’t used their token on kTest.
I don’t think it’s implemented on kOBT yet, since it’s only a max of 3 additional runs for Lv 90+ dungeons, with Lv 90+ dungeons being limited to 2 runs daily. It was mentioned on the website though:
Expect it to come in the future if the information in this notice will stay the same. Probably when they open the TP Shop and the ability to purchase TP.
