Damper node: avoid damp from 0 to 1st val

hello,
attached is a patch which shows my idea on how to avoid the damper node to damp(slide) from 0(in my case -2) to the first given value. the filter time of the damper is set to 1 when the second value change happens.
has anybody an idea how to make this intelligent and more sophisticated?
thanks in advance!
cheers
