I don't think so. At least not easily.
You could make a function to do so, though.

As depesz said, a trigger is possible, but very tricky. I was never able to find a good trigger-based, solution to these kinds of updates for pg_partman myself. Thankfully support for updates that move data between child tables was added for native partitioning in PG11. I would highly suggest planning an upgrade to your major version of PG. Skip 11 and go right to 12 or 13. An upgrade would be arguably easier than trying to code this yourself. And the added features to native partitioning in 11 and above will make managing them far better in the long run.
