Simple op amp question

[J. Larry Hendry]

A simple op amp question:

OK, I am looking at an existing circuit here and not starting something from
scratch.  Let's say I have an op amp wired in a simple inverting fashion
with the input resistor and feed back resistor sized the same providing
unity gain for the sole purpose of restoring the proper phase from a
preceeding inverting stage (like a summming amp).  It appears to me (I have
not tried it yet) that a simple switch wired from the inverting input to the
output (shorting out the feeback resistor) could serve as a phase reversal
switch effectively bypassing that unity gain inverting amp.

Am I thinking right?  It has been my practice to short the unused amp in a
dual in this fashion if it is not part of the circuit.  So, I cannot see why
this would hurt the amp.

As always, thanks for the help
