Younited via Raisin, joint account?

anyone know if it's possible to open a joint account for a Younited via Raisin Term Deposit?

also, am I correct in understanding that the 5 yr Term Deposit at 3.5% is compounded annually resulting in a €50k deposit ending up at €59,384, before DIRT?

Thanks in advance

I asked Raisin about joint accounts and they told me they don't offer any, only solo accounts.
