alternating flashing lights

I am new to deviation and need a bit of help. I recently purchased a T8SG V2 Plus and I have to say I am impressed. So far, it is a great little transmitter. I will add voice shortly and I think it is likely to be my favorite going forward.
I have several planes that I use a standard servo channel to turn leds on and off and cause them to flash. In my Taranis I programed a servo channel to turn on and off at a 1 second interval to make the LEDs flash. Can I do something similar on the T8SG?

Thanks,

And it works perfectly! Very impressive. The only tinkering I had to do was moving the endpoints a bit to make the flash feel good. An easy solution that has a lot of possibilities.
Thank you very much!!!!

For anyone who is interested here is the INI file to make flashing lights on channel 5. The result is a pure square wave and on my jumper the rate is controlled by AUX5. In this INI the three position switch A controls on/off/flashing.

On the model end the receiver is connected to a servo board salvaged from a stripped servo and the servo motor connections drive LED's.
