Adjust actions so that they can deal with variable input

Hi Dmitry,

Sometimes I have a use case in which I want to use an action (e.g. merge another table). I select the columns to add from the second table to the first table. If for some reason the input table changes year to year, the execution will stop because EasyMorph will say that a column no longer exists.

It would be nice if there’s some workaround so that you can select all columns to be added in the merge also if the input changes.

Kind regards,
