I have made a workflow where I calculate two linear regression models, each with the same dependent and independent (target) variables. In the first, with the help of a “Group Loop Start” I obtain the models of the different categories of a segmentation variable called “Banks” and in the second I obtain the results without segmenting (The regression to total). Finally, I concatenate the results of the two models in a table.

If I wanted to change the variables in the regression nodes for different ones, I would have to open each one and change them. I would like to know if there is a possibility, using a node or something similar, to define the dependent and independent variables (only once), and have them selected at the same time in each of the two regression nodes and not have to open each node to change them.

Could you please tell me if it is possible to do this?
