Enhancement request for DirSync task

I would like to see a couple of enhancements for the upcoming V11 DirSync task.

As far as I understand, the mapping of AD attributes to Notes items is static.

I would like to see a possibility to make this configurable. At midpoints, we have a data.sync tool that allows to configure which AD attribute is written to a specific Notes item. This was a common requirement from our customers.

Also, we allow to concat attribute values

"string":attribute1:attribute2~notesItem1
attribute3~notesItem2
... 

For the group sync, I would like to have the ability to add a (configurable) prefix to synced groups. This can avoid conflicts with existing groups and also makes it easier to identify groups that are not created in the Domino Directory

SomeGroup from an AD would become prefix_SomeGroup.
