Re-arranging rows based on pre-defined order

Hello everyone,

I would like to re-arrange the rows of data on a pre-defined order. For instance,

BAX
BAX

CGB
CGB
CGB
CGB
CGB

OGB
OGB
OGB

OBX
OBX
OBX
OBX
*spaced 3 rows apart from each other, and # of rows not fixed.

I would like to rearrange it based on pre-defined order of: BAX & OBX, then CGB & OGB, so, the desired end result would be,

BAX
BAX
OBX
OBX
OBX
OBX

CGB
CGB
CGB
CGB
CGB
OGB
OGB
OGB
