How to specify the '__ARM_common_switch8' function address

Dear Sir,

     In my project, when the switch-case logic exceeds 8, the i.__ARM_common_switch8 function will be called in the assembly code. I hope to specify the address of i.__ARM_common_switch8 through the scatter file.
I tried to specify the address by using *armlib* (+RO) in the scatter file, but it didn't work.
Please tell me how to deal with it, thank you.

    Platform and compilation environment:ARM Cortex-M0 @ keil armcc V5
