Temp Columns LikeTransview

I am trying to figure out how i would go about adding columns in my dashboard that are updatable by calculations and transview like in nature

You can use the calculation widget in an event to set a field with a calculated value, could be a transview field or any other field. If your calculation is very complicated though, you might be better off using a function to do the calculation and then row-update to write your function output from actionResult to a transview field.

I am understanding what you are saying. My question would be how ?

DataViews in AppStudio/Kinetic are dynamic, they can be created at will (with n number of columns) and columns can be added dynamically.
To add a column, simply set that DataView.Column to a value.
For example, in row-update widget, you can do this, with no prior setup:

and from then on, you can access the value in that dataview.column with {AnyDVName.AnyColumnName}
