Pascal,

This then comes down to two questions. 1) Who is going to do it, and 2)
How much are you willing to pay them. Sorry, but if the problem hasn't
spurred someone to add this feature, and you aren't willing to do the
work yourself, then paying for it is your only other choice. I believe
the code needed will be relatively trivial, but probably implies between
2 days and a weeks work to get the code going and fully tested.
