为此，您需要提前知道可能的目标步骤...

To do this you'd need to know the possible target steps ahead of time...

(大多数情况下)JSL被预先解析，因此您无法将"to"值放入任何可以由步/决策器处理的结果解决的值中.

The JSL gets parsed up front (mostly) so there's nothing you can put in the 'to' value that would resolve with a result from the step/decider processing.

可能是有趣的规格更新可能性.

Might be an interesting spec update possibility.
