Movement Request and allocation .

We had some queries reqarding replenishment of movement requests.

1.In the movement request task creation we are using LPN as splitting criteria so its sorting the task by LPN number .Is there any way to sort task by allocation sequence and not the LPN number while still splitting by LPN

2. Also we are using one of custom decimal field on movement request as allocation sequence and use that in the sequence for the replenishment template . While the movement request does get allocated based on the sequence the tasks are not ordered the same way and any task can come up in the list . Is there any way to sequence tasks as per the sequence in which movement request were considered by allocation wave.
