I use umbrel to estamblish private LN channels so i can top up my spending wallets when applicable. here's my question:

Can i splice additional sats into already established channels? I had one with robo sats and one with ASINQ but then robosats had the issues that force closed a lot or all of their channels. I'd like to take those sats (that are now just in my hotwallet) and splice them into my ACINQ channel to make it bigger.

Is this possible through umbrels OS?
