Hi, I think there is a setup described in #624 that might help do what you want, but it is not perfect- see the proposed patch in #625. I wonder if you could help test this? If so, we might be able to land #625.

hi @mostynb, thanks for your quick response.

Yes, I'd be happy to help with testing this, but I'm not very familiar with bazel remote, could you tell me on what needs to be tested? How to verify that expectations are met? Or do we just need to verify whether the modification time has been updated? Thanks.
