Would be very useful to us if allocation is set to "Total Hours" on a project, planing would use all available time instead of spreading even.

So we could set a total amount in the beginning and then drag-expand the project until all needed time is planed. No matter which other projects or events are in between. Now we have to split everything if just a single 50% weekly repetitive event is planed.

This could be implemented as a setting on the allocation dialog - spread even or use available resources
