Constant combinator with input

[Shia]

Like a lot of ppl, creating something for circuit networks, it would be extremely useful to have either

a constant combinator prototype with separate input/output connectors
or
an arithmetic/decider combinator with a direct output setting

Right now, only a constant combinator can output multiple (non-input) values but that leads to problems as it detects its own output signals.
if possible.... pretty please
