SSD boot order problems. Triple booting with Win 7, Win 8.1 and Win 10 TP

Looking for some advice. I have a system with a Asus Maximus V Gene mob, I5 3570k processor, 16 gb ram and 3 SSD's
Win 7 HP 64 bit on Samsung 850 SSD
Win 8.1 pro on Samsung 840 SSD
Win 10 TP on Toshiba SSD
See attached spread sheet for configurations.
I want the SSD 850 with Win 7 to be the first in the BIOS boot order. The SSD 850 is faster than the other SSD's and I want a quicker boot.
Windows 7 is the default OS using Easy BCDEdit.
Thanks in advance.
