Multiple content scripts with different "run at" values in manifest?

Is it possible to add two content scripts to a url through the extension manifest and assign each a different “run at” value?

I want the first script to request HTML content from the background script and the second to run only after it has loaded.

I’ve been using tabs.executeScript to run the second script but wondered if it could be done through the manifest also.

Thank you.

I don’t think there is, however you should be able to get the equivalent of the later events from an injection at the earliest time. All you have to do is make your code wait for the appropriate state.
