Prioritize loading an events file

Lets of experiments

/some/path/mnist_experiments/
/some/path/mnist_experiments/run1/
/some/path/mnist_experiments/run1/events.out.tfevents.1456525581.name
/some/path/mnist_experiments/run1/events.out.tfevents.1456525585.name
/some/path/mnist_experiments/run2/
/some/path/mnist_experiments/run2/events.out.tfevents.1456525385.name

I would like it so that in the tensorflow gui I could tell tensorboard to load a specific events file first.
I would eventually like all of them to load but sometimes after I restart my computer I am in the middle of a training run and it loads that one last when I would like that one loaded first and then the other ones so I can compare and make sure it is doing the correct thing.

For example I have the list above

/tensorboard --logdir /some/path/mnist_experiments
Then I run this command but in the gui I can click something like "Load Now" next to the events file I want to load first. Like events.out.tfevents.1456525581.name

Start by tracing how TensorBoard discovers event files from the provided --logdir path and how the GUI currently loads them. Identify the loading order and the control that would need to trigger one selected file first; done means a user can choose an event file to load before the remaining files and compare the resulting runs.
