set_false_path -from {ModA:ModA_inst|reg_src[144..244]} -to {ModB:ModB_inst|*} ?

I have a 2048 bit register that has a range of signals that need to be part of a false path. Instead of creating 100 lines like this: set_false_path -from {ModA:ModA_inst|reg_src[144]} -to...

Thanks. This version worked: 

set_false_path -from CommandRegisters:CommandRegisters_inst|reg_command_bits -to {MetaDataGenerator:MetaDataGenerator_inst|*}

Having extensive programming experience, it is a mystery to me why anyone would come up with something as ugly as TCL. For example, adding in the {} around the 'from' path above should create a list with a single item but that fails. I'm sure this has to do with some string-substitution rule in TCL...

The last time i looked at anything this ugly, i think it was C++ templates!

Anyways, I now have a working solution. Thanks, all, for your help.
