Is there a "step back" function

Hello, I'm customizing an interface, but I need a function now. I can't find it there, or whether linuxcnc has this function. Whether there is a "step back" function when executing G code. I found that it has the function of "step".

The included sims of PlasmaC and QtPlasmaC have that feature, pretty sure there are other sims that use it, search for "jog while paused", not sure if it fits exactly what you need.

Hello! Thank you very much for your answer. I may not have expressed my question clearly. The fallback function I want is to return to the G code executed on the previous line. Can this be achieved?
Thank you again for your reply

linuxcnc does not have a step back function.
It has a reverse run function or run-from-line function.

Hello, thank you for your answer. What is the reverse run function or run from line function you said, and how should I use it
