Is there a way to create a custom text field inside the account template that goes full width just like the original "Description" field?

 

Whatever custom text field you create only goes in one column of the template, leaving the other half empty. I need to create one field that goes full length, just like the original "Description" field works. How can this be achieved?

 

illustration:

 

This is what I get:

 

[     custom text field  column left     ] [                 column right                   ]

 

Even if the space in column right is left empty with no field, the custom field in column left stays within the border of column left and just never spreads out over the right to occupy the total width of the screen. When creating a custom text field in column left, what we'd like to get - if we leave column right empty with no field - is this:

 

[                                     custom text field column left                                 ]

 

This is how the "Description" field originally works. How can a similar field be created?

 

The reason for that is that whenever we enter some text in a text field that one goes in one column, the space is too small for the default text to wrap nicely and we end up with a totally distorted column vertically which is, as a result, pretty awfull and visually spoils the template.
