Juntar flows

Hola, primeramente desear un buen año.
Qué hay que hacer para juntar los flows que se han dividido?

If you split the flow into two recently, you could do Edit > Undo until you’ve undone the split.

If you split the flow into two ages ago or in a previous session, you’ll need to select everything in the second flow, copy it, and paste it at the end of the first flow. There isn’t an automatic way to “join” flows, unlike there is for “splitting” them.

Thanx !
