Return the last created row (ID) inside a bot in order to use it inside the bot

[DroidTeo]

I think it is very useful to be able to retrieve (return) from a task the ID of the just created row. 
Within my experience as developer, it is something that it used a lot of times and that can be really helpful. 

Here what I mean:

I would like to recover inside a boot the ID of the just added line (Table2) and then, add this ID inside a line of Table1 (modify an existing line). (note this line is the final step of my bot).

Note: I've also asked for this, but as I understood it is something that cannot be done and so, because of this, I'm asking this as a feature.

Note: as I answered inside my "original" post, for me, MAXROW is not the answer -> concurrent access..
