Ability to set exec_properties for a single mnemonic

Hi,

May I ask a question that whether bazel can add exec_properties to a specific mnemonic ? My goal is to assign all CppLink actions to specific remote workers.
It looks --modify_execution_info can add tags to specific mnemonic, but it is not able to add exec_properties. And the platform configuration is not able to limit the exec_properties to actions with specific mnemonics.

So I just come here to find some help, thanks!

No file, test, or entry point is identified. Start by tracing how --modify_execution_info and platform exec_properties are represented, then determine whether properties can be scoped to a mnemonic such as CppLink. Done means an agreed, documented, and tested way to target those actions.
