We're not allowed to do amendments. We can only do amendments to the bill that were submitted prior to 4 p.m. on Friday.
For those amendments that were submitted prior to 4 p.m. on Friday, we can do subamendments. This change would require its own amendment, and therefore it's excluded by what we're allowed to do under the terms of the House order.
Potentially, though, we should make a list of these things and deal with them at report stage when it gets back to the House.
