joining multiple result sets (example sets) and exporting them to a file at once

Hi guys,

I have N variables with their historical evolution...for each variable I build a linear/quantile regression with several predictors (day of week, day of month, holiday etc) to forecast daily values for those N variables one month ahead.

In the end I get N example sets (predicted) with the same number of rows/examples and the same ID...I would like to join them all at once and write them to an excel file, the problem is that the join operators supports only 2 example set while I need to join N at once.

Is there a way to do this without using join iteratively N-1 times?

Thanks a lot in advance

Here is a rough scheme of what I want to do:
