Place precompiled lib (.a or .o) in a specific memory section

I have a precompiled library CustomLib.a that contains several obj files .o

It's possibile to force the linker to put some of object files in a specific location in memory ?

I know that it is possible to put code or variables in specific section with __attribute__ (section(".MySection")) keyword, but i don't have the c source code of this precompiled library.

Thanks,

Davide
