Calculating Iteration Begin and End Dates

If this is my planning tree:


release 0.1 - [dateStart], [dateEnd], [iterationDays];  

iteration 1 [iterationSequence] (int i; i in {0,1,...n})  

storyA;

storyB;

...;



iteration 2;

...;



release 0.2;

...;


then, this should provide sufficient data for iterations to calculate their own starts and ends:



iterationStart = release.dateStart + release.iterationDays * iterationSequence; and

iterationEnd = release.dateStart + release.iterationDays * (iterationSequence + 1).


Correct me if I am wrong, but it does not look like I can do this in Mingle because parent properties are invisible to descendants?




If so, is there any other way with which I may be unfamiliar in which this can be done?



Best regards,



Wil
