How to add to 'Common Expressions" in Access?

Question

In Expression Builder dialog of Microsoft Access there is an entry for Common Expressions. Can I add my own expressions to that list?

Answer 1

In short, No. User-defined functions are not allowed in calculated column expressions. Be aware that calculated fields cannot call user-defined functions. In addition, you must supply all parameters for methods that you call, even if the parameters are optional. (Provided by: Ken Getz, MCW Technologies, LLC)
