Import row but also make edit to row

Help

Hi, I have a datatabledt and a clone copy clonedatatabledt.
Then a for each row in clonedatatabledt , if it fulfils certain criteria, I will use invoke method - import row from clonedatatabledt to datatabledt.

But i would like to modify one of the column for each imported row and the original row in datatabledt.
How do i do that?

Example:
datatabledt:
ID Name Remarks
001 A
002 B

For each row in clonedatatabledt,
if ID = 001, then import row from clone to datatable

Existing Output: datatabledt
ID Name Remarks
001 A
002 B
001 A

Intended output: datatabledt
ID Name Remarks
001 A Entry 1
002 B
001 A Entry 2

In this scenario, when you loop and take the clonedt row to be written into datatable, u can first check if the row exists and then you can get the count of it and then put your value as Entry <count+1>
