Real work allocation : how to disable alert window about future allocation ?

Hi,

In our context, we plan lot of fixed activities (meetings, resources unavailability, support charge all mornings every two weeks). Our questions are :
- is it possible to avoid or bypass the popup windows alerting about inserting future work allocation ?
- could it be possible to have a functionality that permits to set easily cyclic fixed work allocation on a target time window ? (for example: affect a resource to an activity (or a project) 0,5 day all days of a week, every two weeks from 1/1/2016 to 31/12/2016 ? Or, another example, book 0.25day all mondays for a meeting).

Thank you for your support.
