If you're talking about circular rebalance you can pick outgoing and incoming channels with tools like thunderhub and ride the lightning. I'm not sure if those are available in CLN though, I only used LND.
If you're talking about picking an outgoing channel to pay someone else I'm not sure you can pick, but you can query a route before you pay using ride the lightning.
Yeah, I'm taking about circular payments. I tried this with lightning-cli
lightning-cli rebalance
But I get this error message
WIRE_FEE_INSUFFICIENT
Also, I use Ride the Lightning, but the rebalance option is not in the GUI anywhere like it shows in the documentation and YouTube videos.
In RTL of you look at your channel list I think there's something on the right side of every channel that you can click on and it gives you the option to rebalance there.
