Results of a calculation as a value list

[Lougee]

Basically the title says it all. I'm wondering if it's possible to create a value list whose values are the result of a calculation. For example, an event that begins on 1/1/2010 and ends on 1/5/2010... Is it possible to create a calculated field that would return a list of the dates (1/1, 1/2, 1/3, 1/4, 1/5) and could that list then be used as a value list for a drop down field?

TIA
