Run GDB commands on debug

I'm trying to use JLinkGDBServer to debug on a Nordic nRF52832 using CLion. The problem I have is the application is already running when the debugging starts. So I need to run

monitor reset

continue

To reset the device. In ~/.gdbinit I added:

define target hookpost-remote
monitor reset
continue
end

My application is currently hitting a SIGTRAP due to a bug, so execution is paused when the debugger starts. When I debug in CLion as normal, this happens:
