Amend Startegy Add Tasks and Delay Dates

Content

We have two requirements that the collections screen does not seem to be allowin us to action, are using the standard out of the box collection roles.

1 Ability to add an additional task, the ok box is greyed out.

2 Ability to amend the dates of the current and next task.  For example we are on day 28 the customer promises to pay by day 33 but our strategy has pass to DCA on day 30 which we want to delay (not skip) till day 34 (adding in the date if needed).

Are either possible I cant see any setting that might affect this and have come up blank on my oracle suport links.
