Setting a cell to a fixed value

Hi,
I would like to record automatically the date a certain record is created in a cell in Quantrix – like you would do in a database.
To do this I need to be able write (in early times one would have said “poke”) a value into a cell. A script could do it but this would need to be triggered somehow. Is there an internal “poke” function or something similar? Then you could use something like “if(isempty(), poke(date),value). Any suggestions are welcome!
