And yes, while this is possible, it just seems very "difficult" at best, to
be able to create a patch and lay it out in such a way that you can make
those sorts of selections. LOTS of planning would need to go into such a

What I generally do *if* I'm doing dynamic patching is write as much as
possible into an abstraction and just create copies of that. nqpoly4~
may help with automating that.
A very useful trick for these abstractions is to avoid doing connections
at all and just pass $0 as an argument. Then inside the abstraction, use
[r $1-inlet] receivers where $1 is the $0 of the parent as passed as
argument instead of inlets, and [s $1-outlet] instead of outlets. Outside of
the patch use [s $0-inlet] to write to the fake inlet, and [r $0-outlet]
to read from the fake sender outlet. Do the same for signals with r~/s~
and throw~/catch~ pairs. Most dynamic connections can be avoided by this
approach.
If you need to pass data from one dynamically created abstraction to
another, use a similar approach with numbered arguments. Again this can
be seen in action in the redesign of nqpoly4~.pd that I once did and
that's in svn/pd-extended as well, or in polypoly.pd.
this is basically the approach, that probably all dynamic patches from
netpd are based on. no connections are created or deleted dynamically
(it's just too cumbersome and relies on undocumented features).
parts that need to be deleted separately go into their own subpatch, so
that they can be deleted simply by sending 'clear' to the appropriate
subpatch.
however, there _are_ issues, that cannot solved that way. whenever
signals are involved with dynamically created abstractions, it's likely
to get one-block-delays due to the creation order of the
[throw~]s/[catch~]es and [send~]s/[receive~]s. don't know how to deal
with that yet.
