Glad it works for you.
You can probably avoid creating and removing the column. Instead empty the template when you don't need the value. The easiest way to do that is to click on a cell in the column and press F2 to edit the template. Evaluating an empty template is very fast.
Another possibility is to limit searches to a set of columns that does not include the new one. You do this in Preferences -> Searching.
