Trading 212 invest - separate portfolios/subwallets

Hello everyone,
I’m looking for an option, in my trading account (invest - real money), to divide my deposit into separate “subwallets”; that is to have ex. 10k monies, and 1k monies being accounted for, and having stocks I buy for that money assigned separately, even if I buy the same company from those separate pools.

I just can’t find it, or 212s simply don’t have that feature?
