Impossible to use elapsed days

[ygitted]

In MS Project, one could use "elapsed days" for duration definition (ed) instead of days.

A task requiring 10 days would span on 2 full working weeks of 5 days, but a task during 30 "ed" would last 1 month.

This is particularly useful when mixing "effort driven" tasks and "contractual / administrative" duration.

This should be integrated in Project Accelerator to make it compatible with the current practice of MS Project
