G28, G32 and G29 when using multiple z-axis stepper motors?

I am a littlebit confused about all these possibilitys when homeing. At the moment, I have installed 2 ballscrews with a stepper motor on each.
The procedure if I want to print is now the following:
- G28 X,Y
- G28 Z (z will be probed in the middle of the bed)
- G32 (to define auto bed compensation- 2 points are probed, each point next to one of the ballscrews)
- G29 - mesh bed levelling to calculate a perfect plain surface while printing.
Wouldn't it be easier to implement the G32- procedure into the G28 z file? So if I would like to home z, both points would be probed and the best leveling would be used? Or isn't this possible and I really have to home Z at first with onyl one point? (maybe you could just reduce the procedures needed?)
Would be happy for help!
You can Include the G32 procedure in the Z homing if you want, all you need to do is include the G30 commands from bed.g into your Z homing sequence in the homing files.
