Marlin homing axis order and endstops behavior

When I press the home button on pronterface my machine is homing in that order: X-Y-Z.
Is it possible to change this order? I want to home first the Y axis because I have binder clips on the left of the bed and my fan duct crashes on them.
I manually home Y or raise Z before homing to prevent this but I'd like to change it permanently on the firmware.
Is there a setting on Marlin to raise Z before homing XY?

When the printer powers up it assumes it's on 0,0,0 position. Is it possible to prevent movements if it hasn't triggered the endstops?

Thank you
John

When you slice a new part, you can change the behaviour at the start/ end of the print.
This should solve your problem.
Cura lifts the extruder 25 mm at the end of a print. Then homes x & y

Or you reduce the table size, such that the extruder doesn´t come close to the binder clips.

Thanks for your reply.
I have done this (edited start code on slic3r to lift the nozzle before homing) but I'd like to know if there is an option to change this behavior on firmware.
The problem is when I press the home button on pronterface by mistake.
I would prefer to home the Y axis before X when I send the G28 command. Is it possible?

If you're using one of the latest development-versions:

Condig_adv

#define HOME_Y_BEFORE_X

Thank you, that's exactly what I was looking for.
