in the G-code]/select Extruder tab you can modify the temp change behavior. I had the same problem you did. Here is what I did to fix the problem. Every time a temp changes on an extruder, the z axis increases by 5mm and then the print head goes to 5,0 (x/y) position

; Select new extruder
T<EXT+0>
; New tool set/temp change
G1 <Z+5> ;Increase z by 5
G1 X5 F3000 ;go to X Axis 5
G1 Y0 F3000 ; go to Y axis 0
M109 S<TEMP> ; set temp and wait for it to get there before doing anything else
