Run Parameter input should be text area not simple text

I am using the run parameter input to enable the client to enter a text string to be used in a merge document (the footer text). This text changes regularly month to month - but it is the only text on the template that changes - hence using the run parameter.

Currently the input for this is a single line input that does not wrap within the container.

Please change this input from text to become -> text area so the user could adjust the size of the input display and be able to better review their input value, especially if it is long >100 characters
