Feature request: Ability to drop repo map the same way you can /drop files and /clear chat

[vais]

Working in a large repo, a long-running aider session in a vim terminal buffer to the side, I periodically /drop files and /clear chat history as I move on from one task to the next.

I often ask aider to make simple localized edits that do not require knowledge of the entire repo, only the file that I'm currently editing. Or simply /ask it off-topic questions that have nothing to do with the current file, let alone the entire repo. Like, asking something about a language feature, or for some help with an algorithm.

Unfortunately though, every time this happens, aider is also sending the repo map, which can be wasteful.

It would be great to have a command similar to /drop and /clear, but for the repo map. (And, of course, a command to re-enable the repo map before making the next set of requests that warrant it).
