Is there a way to select multiple fields to add together in one go rath

Is there a way to select multiple fields to add together in one go rather than having to add each individually? For example in Excel you'd do (a:z), I'd like to select multiple fields to add together.

To my understanding, you are referring to the "Add Field" option in Form Calculations widget

and the one in Update/Calculate Field conditional logic,

We would like to apologize for any inconvenience. I'm afraid that there isn't a workaround to meet your requirements. Fields can only be added to calculations one-by-one (individually). The only field that allows this is the Input Table field when you like to include multiple sub-fields in the calculation.

We can submit your concern as a feature request to our developers. Just please confirm that I was able to understand the feature you are looking for correctly before we proceed in doing so.
