Can I adapt the Caseta Switch + mechanical three-way installation to multi-location?

I have just installed a Caseta hub and plug-in controller as part of the conversion to a less-stupid home. So far so good, and plans are in place for some of the simpler one-way and three-way upgrades.

I am also exploring using a Caseta switch (6ANS) to replace an existing 4-switch configuration that controls fluorescent and incandescent lights in parts of the basement and, most importantly, the basement stairs. This is part of a plan to replace the "bulbs" with non-dimmable LED without replacing any fixtures.

I have gone through the Advanced installation document.

I understand (more or less) the Caseta switch + mechanical in a three-way configuration, and the Caseta switch + Pico On/Off remotes in the multi-location configuration.

Is there some way to adapt the mechanical option to the multi-location situation? I know (the hard way) four-way switches are more complicated than three way (which are complicated enough). All of the electrical boxes have a neutral wire available.

I'm a little worried that the farthest Pico remote might be too far from the switch although the Caseta hub is definitely in range.

Thank you for this.

UPDATE: I did search extensively before creating this post, however this popped up which answers the question (no).

If everything is in range of the hub you are good. The hub will act as a repeater and relay any signals in its frequency range.

You can also add 1 plug-in dimmer and program it to act as an extender.

Thanks for the info. I had previously added the plug-in dimmer and it automatically chose to become a repeater. I'll see how the 4 switch installation goes.
