is it possible 2 use channel/attr. editor's translateXYZ 2 set LOCAL transformation?

like:
1.box moves from frame #1 to #10 along axis x
2.#10-#15 box rotates along Y, so object's x and world x r not paralell.

is there any way, to use channel's tx entry 2 move box along object's axis? if i use move tool with objects' axis setting, that changes tx as world coords.

in other words, can i set up tx,ty,tz 2 use object axis movement? maybe,i've totally missed the concept..and cant

i use tz in expression, thats why i need it..

thx..
