Wondering if this feature is available or in the horizon. In MathCAD, we can write sheets/functions in one file and "reference" to a new file. This allows for standardization without having to re-write the functions or calculations into every sheet. It is known as "Insert Reference"

E.g. On large projects with multiple, similar files (ie a large bridge with many piers that will have similar designs). In MathCAD, specifically build a sheet that contains global functions, which is then referenced by the other files. It functions to extract data from external databases, design equations, calling other programs, etc. It's more efficient to write (and edit) those programs in only one location, rather than in a collapsed utility area within every separate file. Obviously it depends on the workflow
