Include support for formula columns

[ArneRustad]

Tool
AttributeManager

Is your feature request related to a problem? Please describe.
It is very frustrating that the Attribute Manager does not support formula columns, which leads to a lot of extra time consuming work when columns of this type have to changed or even columns referenced in the formula of a formula column have to be changed.

Describe the solution you'd like
Support for formula columns. Formula is automatically updated when one of the columns it references is updated. Does not throw an error when a regular column is changed but it is referenced in a formula.

Describe alternatives you've considered
Use another tool. Delete column and create from scratch, but this leads to data loss and it becomes quite complex when a regular column is referenced by one or more formula columns.

Does it not show up in the tool, or does it error when you attempt to run it?
