Sure.
In the United Kingdom, they have a system that's based on just the honour code—and it's had problems in the past—but two members can pair and then you can go and inform the whips that you are paired for whatever length of time you need the pairing for.
Pairing has been used routinely in the past, but in the early 1990s, Standing Order 44.1 was changed to include the whips. Since then, the whips have almost exclusively had control of it. However, over the decades as whips change—and you know this, having been a former whip—there's a lot of knowledge that needs to be downloaded from whip to whip to whip as that role changes. I just think that we as members are able to find members who we agree with and who we build a relationship over time with and that, based simply on a handshake agreement, we can inform the clerks and the whips after the fact that we are to be paired for a vote. The way the system works right now, there are all those books and binders on the table in the chamber. Those are not just for decoration; they're actually useful. One of those binders is a pairing binder, and within it, the whips have to sign the names—not the members.
