Manually assign Liquidity item - S/4 HANA

Hi,

I am currently working on/ customizing the Cash Management module in SAP S/4 HANA. Precisely, I'm dealing with the Liquidity Item derivation.

From the old Liquidity Analyzer I know there was a transaction (FLQAM) to manually assign a liquidity item.

I'm wondering whether there is an equivalent transaction in the new Cash Management powered by HANA to accomplish the same?

An explanation or hint would be greatly appreciated!
