Tagged Value type for JavaScript formula?

[Brad Dillman]

I wished EA worked a little more like a spreadsheet, where I could just go to something like a tagged value and enter a constant or a formula. Just let me throw a single line of JavaScript in (say, as a Tagged Value type) and let me access some simple things directly as JavaScript variables, like a 'Value' field of a contained Part or Property, or something like that. Something simpler and lighter weight than drawing a whole SysML parametric diagram. It would be useful for totaling up values for sub-components on Object diagrams, IBDs, etc. Rather than display the content of the tagged value (the formula), display the result of the formula.
