Invoice template issue

Invoice template issue


On my invoice template: the tag :

Invoice Total: %Total%


would render something like :

Invoice Total: USD736.85
Invoice Balance due: USD736.85


I don't like the format "USD736.85" because when I search for the amount 736.85  in Gmail it does not render the right results.   I recommend using "USD 736.85" instead of "USD736.85".   Note the space?
Thanks!!!!
