Form: How to change the font into TextFields globally

I would like to have typewriter-font into my pdf-form.

So I find out the mechanism

TextField[width=5cm, name=NAME,value=Font manually changed,
format = { var f = this.getField('NAME'); f.textFont = 'Courier'; }, 
]{B: }

depending on the name of the textfield.

I can do this smarter using a corresponding command, but I ask myself:
Is there a possibility to set the font globally for all textfields?

documentclass[fontsize=14pt]{scrreprt}
usepackage{xcolor}
usepackage[]{hyperref}

% Gobal Styles
defDefault{
print, bordercolor=red,backgroundcolor=lightgray,borderstyle={U},
}
xdefDefaultOptionsofText{Default}

begin{document}
begin{Form}
TextField[width=5cm, name=a,value=Default Font]{A: }
TextField[width=5cm, name=b,value=Font manually changed,
format = { var f = this.getField('b'); f.textFont = 'Courier'; }, 
]{B: }

Let's do this with a newcommand:

% TEXTFIELD[<opt. Arg.>]{<name>}{<title>}
newcommand{TEXTFIELD}[3][]{%%
TextField[width=5cm,
name = #2,  
format = { var f = this.getField('#2'); f.textFont = 'Courier'; }, 
#1, 
]{#3}
}%%

bigskip
TEXTFIELD[value={Font changed}]{C}{C:}
TEXTFIELD[value={Font changed too}]{D}{D:}
end{Form}
end{document}

documentclass[fontsize=14pt]{scrreprt}
usepackage{xcolor}
usepackage[]{hyperref}

% Global Styles
defDefaultOptionsofText{
 print, bordercolor=red,backgroundcolor=lightgray,borderstyle={U},
 format = {var me = event.target.name;  
          var f = this.getField(me); 
          f.textFont = 'Courier'; }}

begin{document}
begin{Form}
TextField[width=5cm, name=a,value=Default Font]{A: }
TextField[width=5cm, name=b,value=Font manually changed,
]{B: }
end{Form}
end{document}
