I would like to know if there is a possibility to make a loop somehow work on orange, where this loop consists of the script (1) pulling one line at a time from the database and throwing it to the models, then the script (2) play the line n + 1, that is, the next line for the test, so that the models perform the forecast; finally, the script (3) stores this and saves these forecast entries accumulated in a single data table. Then, the script (1) pulls line 2 from the database, so lines 1 and 2 are in the training base, and line 3 is put to test by script (2) ... this goes on until all lines 1 ... n are placed for training, while line (1 ... n) +1 is placed on the test. The loop ends when even the penultimate line has been trained and the last tested. It is possible?

Thank you friends!
