Any way to setup Mach3 to ensure that the spindle will not turn on until the direction has changed?

For example;
C6 board is setup for CW/CCW on Relay#2. I am using Relay#1 Enable to turn the spindle VFD on and off (KBIC). When testing my setup I found that in the MDI screen when I issue a M3 command followed by an M4 command the spindle will decrease speed, Enable relay turns off, Enable relay turns on and half a second later the direction relay changes.

Now I do know that in my code I can ensure that I never switch directly from one direction to another without a M5 stuck in between.

Thanks.
