Flow groups are designed to manage multiple threads. They can also be used as presets.
Each group has a mandatory parameter name — name of the band. The name can only consist of lowercase Latin letters and an emphasis symbol, and must be unique to each group.
In addition, parameters can be defined in the group enabled, dst, params. These parameters will be the default parameters for all group threads. Determination of parameters dst and params in the flow, only the values will be used
from the flow settings.
