Like Geert, I don't understand why you want this.  Obviously I have
some wrong model of your situation.   (Which is quite likely, because
you haven't really explained it.)

Can you tell us the underlying real problem that you hope your utility
is going to solve ?  By `tell us the underlying real problem', I mean
to ask for what in engineering is called a Solution Neutral Problem
Statement.
