Ability to rename output when applying formulae to existing fields

[DataNath]

At present, users can create a new field or update an existing one within the formula tool.

When making changes to an additional column, I often have to then add a select tool to rename this (or remove the original column if I make another with the correct name). Therefore, it'd be great if there was an option to rename the output of the formula as part of the configuration. Perhaps a tick box to 'Rename column upon output' along with a text box, where the Data Type selection is.

This is a fairly minor QoL thing but it could definitely trim down the number of tools used in some cases. In terms of referencing the field itself, maybe the formula tool could use [This field] or something descriptive to dynamically reference it, rather than the actual name which will be edited.

As an aside, I'm not sure if it's a technical limitation, but it'd also be brilliant if the field size could be changed for existing columns (within the limitations of the data type), rather than being static.
