This feature request is for a new Action-type that would replace the need for several actions to accomplish the same task:
Update a set of rows using values from this row
Currently we can:
Add a NEW row to another table using values from this row,
and
Execute an action on a set of rows
But to pass values from the current row to a set of existing rows requires a bit more setup. This could easily be defined in a single action and could use the same UI as the existing actions:
This would really simplify a lot of common routines where you want to push a value from a parent record to multiple child records. And I think it would replace the need for workflows in some cases, making the app more powerful when in offline mode.
