Select which saved maps to download

Would it be possible in a future update to be able to select which maps you want to have downloaded on a specific device. Example: I use Gaia on several different devices. My Jeep tablet I like to have my entire area mapped out in case we end up where we didn't intend to. However this also means my phone will sync these maps and store them too. The other convenience would be when I go out without the jeep and want only my cell phone to have a certain map, this lessens the storage across many devices if I was simply able to create a saved map and select it to be updated of downloaded at select devices. Thank You!
