Please help increase size of ppa:canonical-hwe-team/experimental-unstable

In https://launchpad.net/~canonical-hwe-team/+archive/ubuntu/experimental-unstable the Canonical Hardware Enablement Team hosts staging/experimental patches based on linux-unstable to be evaluated/tested for OEM projects. While we use it for regression detection, validity tests, it hits the upper limit 2G right now. Please help increase the hard limit for them to same 8G as others (https://answers.launchpad.net/launchpad/+question/702996) do if possible. Thank you.
