Replicate output of pwm pin on another output pin? Ardiuno Mega 2560

I have a legacy PCB that connects PORTA, pins = {22, 23, 24, 25, 26, 27, 28, 29} to the PWM input of a set of actuators. The accompanying code made use of an interupt service routine to generate PWM signals. This in turn caused all sorts of other problems for the system.

So, I would like to leverage the Mega's internal counters &amp; use the PWM available on pins = {2, 3, 4, 5, 6, 7, 8, 9} &amp; use the analogWrite() function. At present there is nothing else connected to these pins but access is limited.

Before I go down the route of redesigning the PCB I was wondering if it was possible to replicate the outputs of pins {2, 3, 4, 5, 6, 7, 8, 9} to pins {22, 23, 24, 25, 26, 27, 28, 29}?
As Jot wrote, you cannot simply route a signal from pin to pin inside the chip/Arduino. So - unless you redesign the PCP, which would be the cleanest way, or use jumper wires, which is not so clean - you are down to using software PWM. There are also libraries for this, if you don't want to write this yourself, for example the SoftPWM library. These libraries have their own limits, especially in frequency. Be sure to check, if they fit your needs.
