Can you change multiple parameters at the same time?

I use Harmony Essentials, and have some mildly complex rigs, and would like to know if it is possible to change multiple layer parameters all to the same parameter, instead of going through each layer individually and changing them. For example, I am trying to change about 25 layer parameters from 1 to 0, and from 0 to 1.

You have access to the “Set Ease For Multiple Parameters” script/tool
that’s on the Timeline View toolbar. The icon for it looks like two “s”
offset from each other with a red line for each at top and bottom.
This may help, depending on what specifically you need to modify.
