Can IO MUX be used to connect two gpio pins instead of internal peripheral to GPIO?

[greengnu]

The documentation states that IO MUX can be used to connect a peripheral signal to multiple GPIO Pins, so I wonder whether it also allows to connect two GPIO pins directly? If so, how?

If you're happy with translating the input GPIO to the output GPIO, there are special signals in the multiplexer for this.
For example, for the ESP32S3, this is...

There is a range of peripheral output signals (208 ~ 212 in Table 6.11-1) which are not connected to any peripheral, but
to the input signals (208 ~ 212) directly. These can be used to input a signal from one GPIO pin and output directly to
another GPIO pin.
