Here's another option, the other addon I use for all flights, the awesome Self Loading Cargo. Besides its robust flight scoring component which is a nice surrogate for the fact there are no meaningful consequences of making errors in a desktop sim versus RW flight, it also includes a very simple and effective pushback routine for when GSX fails, which is rare, but can happen. In fact, it just happened to me at KLAS. SLC is quite well integrated w/ GSX and this is a dialogue that you control relating to pushback. While default is GSX for pushback in SLC, I had to choose SLC option for pushback instead, which activates it as the pushback routine. What's nice is, compared to default pushback in MSFS, as all commands are instantly enacted, direction changes, stop, etc:

Thanks for that alternative @Noel Much appreciated. I think I'm going to purchase GSX. Whilst I'm currently flying GA, no doubt that in the future I will come to a period of liners.

Don't forget to check https://flightsim.to/miscellaneous/gsx-pro for any modified aircraft or airport profiles.

When installed, there should be two desktop shortcuts. A little counter-intuitive, but to update GSX at any time use the "Installer" one - not the "Live Update" one. Updates are fairly frequent, so keep checking (!).
