DLAU and multiple external address books

DLAU supports estimating CCX user Licenses for accounts found in external addressbooks.
Here I found some optimizations:

1. DLAU does only look into Directory Assistance configured on the Administration Server for additional addressbooks. Member servers could have other/additional addressbooks listed in their Directory Assistand Datebace. These Additional Adressbooks might not be configured on the Administration Server, so they would not be considered during estimation.

2. In case you have more than one additional Adressbooks to store external account informations you only can select ONE of these.
   F.e. one external adressbook for Customers and another f.e. for Vendors.
   Would it make sense to be able to select both for the lookup for CCX Users?

3. In the current version you can select which extentions externel Users might have to be cosidered in DLAU as CCX Users. Unfortunately this selection is not saved for the next report to generate. Please enable to save the last selection for the next execution of DLAU Tool.
