[PD] send messages to different abs with the same name

sorry, it's like hieroglyphes what i wrote.....
i try to get it a little bit more concrete: let's say i want to build an
abstraction [multiosc~] which contains some osc~. let's say the first
argument defines the number of [osc~], the second defines the frequency
and the third defines the intervall to the frequencies of the following
[osc~]. (so a [multiosc~ 4 1000 200] would give you four osc~ with the
freqs: 1000, 1200, 1400 and 1600).
i think the only way to do this, is to build a kind of 'self-creating'
abs. it uses the arguments to create in itself a defined number of
[osc~]. but if i make it 'self-creating', i only can use it oncce at the
same time, which is not the idea of using an abs. when i create a second
[mutliosc~], some new osc~ will be created also in the first [multiosc~]
because both have the same window name. this is why i said, a $0-option
for abs-names would be nice.
has someone already done something like an 'self-creating' abstraction?
or how would you realize something like [mutliosc~]?

p.s.: i'm not a c-programmer, but i think objs like [pack] or [route]
are kind of 'self-creating' too (number of outlets is defined by number
of arguments). i wouldn't know how to build them as an abstraction. but
i think it should be possible to do somehting smilar in pd too.
