how to specify an array in an sdc file

I want to specify an array in an sdc file

For example

set_false_path -from [get_keepers {my_control_reg[7:4]}] -to [get_keepers *]

However I don't think this method works. Do I have to specify each bit separately ({my_control_reg[7] my_control_reg[6] ...}) or is there another way of specifying this?

Thanks
